This leanback is good enough for me to make up my mind about sitting in the corner of my room FOREVER


Normally i learn stuff from watching vsauce videos the only thing i'm getting from this leanback is nightmares


That was disgusting... but thanks for sharing! I love these 'geeky' leanbacks :)


Yea dude, it was very informative. You vsauce guys are great.


whenever i watch leanbacks i lean forward to my screen and after the playlist is finished he says"dont worry you can lean forward now" but i end up leaning backwards


Can't believe I managed to finish a meal while watching this playlist!


I am incredibly itchy now. Not just a normal itchy, but I think I can feel bugs crawling under my clothes.

Actually, the videos were bad enough, but the related videos are SCARY!


When he told me it was going to make the guys cringe I had a feeling it was going to be this fish because I had heard of it before so I was like "Ha, I don't think so" ..I practically had a seizure in my chair watching it swim up to the guy.


now im not eating sleeping peeing in the water or going in the water ever again thank you vsauce for making me paranoid


Well thanks VSauce, I can no longer sleep, eat or go into the water without fear now.


I wont be up all night worrying about the toothfish, I will be up all night worrying about bedbugs :(


I'm more afraid of the bed bugs than any of the others to be honest.


I'll never make fun of ppl who live in basements. Those guys know how to stay safe


I already knew about the bedbugs, horsehair worms, leeches, deadly bowel worms, and zombie snails.

However, I will never go in a foreign body of water again. Good thing I never liked swimming in the first place!


According to that last video if you were paying attention, you're safe as long as you don't pee in the water. Make people watch that video and no one will ever pee in the water ever again... except maybe in swimming pools... until someone decides to fill swimming pools with these fish.


I stopped leaning forward after the leeches. They scare the crap  out of me!
And I will SO never piss in water AGAIN! Thanks VSauce for teaching me good manners by scaring me off :3


The next Leanback better be how to erase horrible thoughts and memories and how to control being freaked out...
-_-


I felt the pain of this guy just when the man started to pee and fish approached him!


I stopped in the middle of the leanback because i had to eat my dinner. I noticed a little thing that looked like a worm.... I freaked out and now my parents think i'm fuckin crazy. Thanks Vsauce :D


leanback is the perfect name for these vids, i always find myself leaning back by the end


I LOVE VSAUCE EVEN THOUGH I AM NOW SCARED TO SLEEP!!!!


NOW I can lean forward? I've been leaning forward with dry heeves since this freaking leanback started! XD


he keeps calling them leanbacks, but with all the stuff i see, im always leaning forward


I DID IT! I finished watching this goddamn playlist!


Im scared of: the forest - ants
the water - those penis parasites
Water - Leeches
Dirt - Bowel Worms

4 traumas in less than 30 minutes.. A new record


Well that was immensely horrifying, g'night everybody! :)


now i will never swim in a lake, piss without a toilet, go to bed without disenfecting my room and sealing outlets, or eat anything uncooked.


There's a lesson to be learned from the toothpick fish:Never pee in the pool


this is the only leanback where im leaning further and further away from my computer screen >.<


I'm worried more about the bed bugs...i think i'm going to put a camera on while i'm sleeping and catch 1 of those, or possibly a ghost!!!


Goldfinger wanted to cut Bond in half from the crotch up using a laser. Bond was ready to talk but managed to escape.

If Goldfinger had a tank with these fish Bond wouldn't have escaped!


i ate through the whole playlist just fine


Thank you. I am now terrified of sleeping, swimming, and eating. completely terrified. so yeah, thanks for that. see ya next week.


Could you do a Leanback on the human brain or dreams?


That does it, I'm never leaving my house again. I'm safe inside! Except for bedbugs, but I'll sleep in a big trash bag from now on.. :|


Could u add tags similar to the video so its in the related videos section? It would make it easily accessible on mobile phone :D


You should have put a video in about Cymothoa exigua. A parasite that lives inside a fish's mouth.


thank you lean back .I am just going to go cower in a corner and never leave it again.


kept my legs together the whole time on that last one...


Okay, now that last video made this whole this worth it. XD


I'm gonna go watch some kitten videos, sure their parasites, but they're way cuter and they won't keep me up tonight


after all this... I feel like a real man


do a leanback on ghosts/paranormal activities!


YES! I finally made it through the parisite leanback...OK! I admit it I skiped 3 videos.


Alright we learned the Lesson: Do Never Pee in the Shower Again!


The wood in the background is legendary.


I'm....I'm just gonna go out into space now. I'll feel safer there....


Did no one realize? That fish is the ultimate solution for those who urinates in swimming pool !


I can happily now say 'nature you scary'.


I'll search for Leanback #6 now, I said. Oh, and I'm kinda hungry, I'm gonna go get something to eat while i watch, I said.
But the universe had different plans...


OMG i will never pee in the ocean again!!! ahhhh ewwwwwww. I will NEVER sleep again, and i will never go outside again. thank you vsauce!


JUST MAKE SURE YOU MADE UP FOR THIS KEVIN.. !


Well to me the moral of the story is to never urinate in foreign water again :D Not like I have done it before xD


is it weird if  none of this has gotten me scared or weirded out


aww i have seen like half of this in my health class, that means i have to pay less attention to watch leanbacks :(


Well, I'll never pee in open water again.


my stomach hurts from the tape worm one D: argh... that's creepy.


hmmm. so now im sleeping with socks, a hoodie, gloves, a mask and pants. scared to poop. and never peeing in water again. thanks vsauce ha


lol, i was leaning back in horror after the last video!  "leaning forward" now! :)


Like leaning forward is what i'm worrying about right now, and right before i'm supposed to go to bed and all ;(


Yay! Tomorrow I'll go to swimming!

*wild vsauce2 leanback appears*

Nope! T-T


That's ONE way to get people not to pee in the pool...


UGH, damn, why did i watch this episode. I was perfectly fine with parasites before. Now i don't want to pee in the water anymore. And my pool is highly chlorinated too. Not enough to kill a human but pretty much anything else it can kill.


he said if you cant handle it, don't watch it! its your fault for watching it to the end.!
and these videos are cool and interesting!


I leaned back in horror after a while....


Ok so that wa a good way to end the swimming season! :D


that last fish thing came straight out of hell!


well, i'm officially scarred...let's all go swimming!


Who else is ready for their doctors check?


I leant right back for this leanback.....Riiiiight Baaaack!!!!!!!!!!!!!!


we should show the kids the previous video and tell them not to pee in the pool or else....


I have the feeling that something is crawling on my leg...


ultimate parasite location:
A mat floating in the amazon in an underdeveloped region. Bedbugs + all the flatworms + zombie snails + the penis intruder....

what a nightmare....


Kevin: "I hope you enjoy...."
Me: *twitching in agony from seeing a fish perforating a p***s from the inside*


Usually I like to eat during a leanback, not this time.


im never peeing in a river ever again...


That is why my dad told me to never pee in the Amazon...


I'm going to have to watch 1000 cat videos to get those images out of my mind...


"You can lean forward now"?!
Oh yeah! Good one! Ha! Ha!


After that last video i won't pee in a river...


Right... Never going to eat or sleep again. I'll learn how to survive...


Im not going to stay up all night because of the toothpick fish.. BED BUGS.


not gonna lie.....
BUT THAT WAS COOL!!!!!


yeah, the only body of water that i'll ever pee in is a swimming pool.


Why did i use my whole night to watch this >.< now i wont get to sleep D:


so that's why they call it the tooth pick fish...oh gawd


well now you scared me for life! i will not eat,sleep or swim again in my life


Can't eat, sleep or take a bath, I guess I'll be on reddit for the rest of my life then :/


might as well do a leanback on the serial killers who live in my area.


The toothpick fish is ganna get you in the shower!!


Anyone else scream because of that damn fish! D:


Go more things to be worried about than leaning forward my friend....


This leanback will give me nightmares.... :(


any one else feeling stuff crawling all over them.....


Who said I was leaning back while watching this?


Ok....lets see now....I don't wonna sleep, eat, go into water, nor pee...


Dam after watching the related videos to some of those has made me afraid to leave the house.

Anybody else click the demons in the stomach video? i think it was related to either the horsehair or leeches.

My butt hurts from the horse hair and my penis hurts from the candiru

By looking at the amount of comments, I think I'm pretty safe to say I like Penis.


holy..fucking..shit..holy..fucking..shit...holy..shit...no..what..the..fuck...holy..fucking shit..what the fuck


My vagina feels pretty damn okay right about now.


Thank you. Thank you very much. FOR FUCKING TERRIFYING ME. I'm going to go live in a plastic bubble now. Goodbye.


i hate the fucking first one so fucking much i hate u guys right now oh god i dont know i managed to survive


F U VSAUCE! NOW I CANT EAT, SLEEP, OR DRINK AT A FOUNTAIN AGAIN!!!


so what did we learn from this? humans are very much like parasites. they look for an environment, exploit it and make it die :)


My dick feels awkward after the last video...is it just me?


there is a parasite that was found near new jersey that survives by attaching onto a fish's tongue and eating it, it then stay in place of its tongue and feeds of food as the fish eats, the fish still survives for a long time after the attachment.

its called Ceratothoa imbricata


You guys found this hard to masturbate to?
CHALLENGE ACCEPTED


I was going to masturbate after this but thanks...... fuck you!!!! lol


anyone else wince when that fish crawled into his dick?


i heard about that legend in science...i think 2 men were fishing and the went to pee and the fish crawled up their penis..


Now I'll even take more care of my dick D-:


OH MY FUCKING GOD IT SWAM UP IN HIS DICK!


Okay im going to burn my bed down toningt, never going the toilet again and never gonna swim in my life. You know what? Im going to life in a hole from now one! GOOD BYE!!


FUCK THIS!!! next time i will swim, it will be with 3 condoms!


Wat about that nasty parasite who lives inside the mouth of a fish, replacing its tounge???


my dick is scared....... thank u i gues :(


i already leaned forward when i grabbed my dick D:


be sure to UNSUBSCRIBE to NEVER EVER see this knid of videos


OH FUCK NO. NEVER AGAIN WILL I WATCH ANYTHING WITH PARASITE IN THE TITLE ON YOUTUBE.


correction: now I can lean back and let go of my dick that I was holding in imagined pain. Toothpick fish = Pure evil


my dick does seem to have gotten quite the opposite of a boner, i think it's hiding... don't scare it


Is it wrong if i say i have the weirdest boner?


FUUUUUU KEVIN Y U NO MAKE NORMAL LEANBACK


I'll fill my swiming-pool with candirus! That way noone will piss in it!
