I'd not had much sleep and was in a weird and very giggly mood.
After everyone had entered their respective cubicles, a dead silence seemed to settle in. I can only assume everyone was waiting for everyone else to break the quiet. There was just the occasional rustle of paper. I decided that I'd do a fake-flush and use the noise as a cover to vent
But before I get the chance, someone in an alternate booth lets out a ripper. I'm already feeling very silly, so I have a little giggle. And in the resulting jocularity, I accidentally do an extremely noisy fart and follow it up by birthing a clinker that must have sounded like a bowling ball being dropped from a mile up (resulting in a REALLY wet bum, let me tell you).
I think this is so funny, I just lose it and begin to laugh hysterically. And the thought of people in adjacent booths wondering what the hell is going on just makes me crack up and laugh even louder. This horrible cycle just feeds on itself and utterly deteriorates into me doing the Dr. Evil insane laugh ("Muahahahaha!!!") whilst farting randomly and uncontrollably and noisily expelling various nasty things. Not even conceiving the possibility of my boss being in a neighboring cubicle could stop me.
Towards the end of this, I could hear several booth doors opening and people washing up and very rapidly leaving.
Overall, it was a very satisfying experience -- but I did have to wait for thirty minutes to be sure anyone that could even remotely link me to the event had left.
