so I've posted this story before, but I don't remember where.
When I was working on my master's degree, I worked in the university's library. I was sitting behind the desk whispering to a buddy of mine about stuff. He is a really nice guy, and super polite and a bit shy. I had my cellphone in my back pocket. I had heretofore not known that I had the vibrate option on the phone, and had somehow inadvertantly set it. While leaning forward, whispering and trying not to disturb studious individuals, my cell phone went off and vibrated in my back pocket. I was so startled I farted.
LOUD
I was soooo embarrassed I blushed. My very quiet, polite friend paused midsentence and then discretely decided to continue as if nothing happened. I was mortified--but it is my second best fart story and it was worth it.
