Farting in the bath

Description YT

The bath is a special place for me, the Fart Master. For it is where I originally founded my skills by mistake, and also discovered that humans (and fart masters) have a built-in reflex to stop water from passing into their bodies from the rear. Why? How does one inherit such a reflex? This is both proof of evolution from fish, and a sign that there is indeed no God. As if I wasn't enough proof of that already.
