BWAHAHAHAAAHAHAHAAHAHAHAAAAAA!!!!!!!!!!!
I'm crying here!
All the laughing is making my stomach cramp.
.....Oh shit.
Giggle farts never end well.
I remember trying to sneak one out in math class...
It was a perfect setup. the air currents in the room lofted my gases over the top of everyone, and dropped them like a bomb on the little gal in the far right row, second from the front... Whereupon she would, upon catching wind of the change in atmosphere, turn around and beat the crap outta the poor fool behind her, him being perfectly innocent and unawares.
Everything started out fine, as a textbook SBD... But it developed into a warbling squeaker... Which of course lead to giggle farts, which always end in... yep.
