Methane and sulfur compounds

Methane and sulfur compounds are stuff that comes out of your butt. It's basically a fart. The methane is the loud part of the fart, while the sulfur compounds are the stinky part. The more sulfur compounds it has, the stinkier the fart.

Ew! Who let out methane and sulfur compounds? It stinks! Stinky fart!
