I've been saying it for years, farts are funny!
Here's the proof.
Certain sports carry with them a certain level of hoity-toity-ness. Golf, tennis and polo are all a little more "white-collar" than some of their other sport peers. I think you could probably add billiards to that mix as well. So you've got a group of people in a room for a professional snooker match and everybody is taking everything SUPER SERIOUSLY.
Then somebody farts...And everybody erupts in laughter! Proof that we're all human. Now the culprit who was probably making fake fart noises as a gag, did it again and the second time around the laughter halted. Still, the first one was a great gag!
