The fart is the central theme for a large category of humour for undeveloped cromagnons.
- I've just farted.
- I've just farted... in a lift!!!
- omg - have you just farted? That stinks.
- Pull my finger.
- Ha ha - I've just farted again!
- Eurghh, dude you need raking out. What the Hell have you been eating - dog food?
