Peter asks the question, “Why are farts funny?” Well, Peter, I’ve thought about this and I think I know why farts are funny. I believe it’s the surprise factor. In comedy, a joke is funny because the punchline is unexpected. A fart is like a smelly little punchline.
This theory is confirmed by the fact that the funniest farts are the ones that are the least expected. For example, a fart is funnier if it comes from someone who doesn’t usually fart or when the fart sneaks up on you in an inappropriate location (Macy’s, church, job interview, etc.).
Even if it’s your own fart and you know the fart is coming or if your dear friend or spouse announces an impending fart, the element of surprise is still there. How will the fart sound? How will the fart smell? Will I gag? Will he hold the covers over my head? Will we eventually divorce or will we continue to live lives of quiet desperation?
In summary, yes, farts are funny. No big surprise there.
