Farts

Farts are a strange, mysterious sound that no one truly knows the origin of. They can be heard just before a poop is released, so they must be related. Sometimes they happen on random occasions too, sometimes not even in the bathroom! They also have an arcane, esoteric smell that comes seconds afterwards, it is unknown is it is related or simply a coincidence. Some scholars believe farts to be funny, but it is universally agreed that poop is funnier. Some conspiracy poop theorists believe that farts are the gaseous form of a singular poop, but no one is really certain if that's true or not.
