As I play in a band who are exept me and another all boys... You kind of get used to this behaviour.

Trumpet trousers!

The best laugh though was in a yoga class I used to go to for years...

Yoga relaxes... EVERYTHING!

and often in class whilst people were stretching, and holding yogic stances or bringing their legs over their heads etc, then someone would uncontrolable let one out. Much to their embaressment, and used to make me and my friend just crack up totally.

Especially when it was one of the more refined looking elderly ladies...

Methane yoga!
