The psycholgy behind a fart: You have something in your nose somebody already had in his arse. And you need to breathe. Childish me thinks that this is hilarious. :)

P.S.: When somebody hugs you, rip one. They think they a strong then.

#5 and then you fart a lot when you come back up, and when you take off your wetsuit, everyone around you gets the pleasure of smelling it ;)

#13, If they fart to say 'hello'......what do they do when they say 'good bye' ?

'exists'? #11

The way your nose works is by inhaling particles and interpreting them as smells. Hence, farticles.

Farts are the ghosts of the food we ate.
