I know it doesn’t have the same humor/horror as pooping yourself but it does seem to be a center of embarasssment/humor (depending who its happening to).
I am a naturally skittish person; if I am engrossed in something and somebody opens the door/taps my shoulder/says hello it will scare the living daylights out of me. Now, if I have to pee really bad and I get startled, well, you can imagine the result.
Once I was playing a game of Starcraft on Battlenet and was involved in a very close match. My friend suddently knocked on my bedroom window (it was late and he didn’t want to disturb other people in the house). I had to pee really bad but wanted to finish the game. Well, this was a mistake because when I heard the knocking sound on the window it startled me so badly I peed my pants. Fortunately I was home so when I let my friend in I told him “Look what you made me do!” :eek: and he cracked up (so did I). Fortunately not mortifying for me, just a little bothersome.
My friend, his roomate, and I all had a weight training class at a nearby community college last year. One day, we were walking to class and roomate had to pee bad. By coincedence we happened to make some really funny remark that made her laugh so hard she peed in her leotard (stress incontinence I guess). Ran off to the bathroom and fortunately she was able to use the hand dryer to evaporate the evidence.
