I will warn you on this....take heed. Being new to yoga 6 months or so via my wife's nudging I am still learning the ropes. On class 2 I found myself in 'The Pigeon Pose'.

I had no warning and managed to lay down a crop duster type fart. The kind that sounds like kids feet skipping hop-scotch down the sidewalk. Apparently a fart in yoga class is nothing new b/c I was laughing so hard I had to break out of the pose and the instructor said ....'oh is THAT how you feel then'. Mama-san gave me the stink eye though...not pleased.

Just be aware yoga can incite mustard gas attacks:)
