Okay, I probably shouldn't relate this one since it happened to the girlfriend of a friend of mine, but it's too funny and they don't live in the country anymore, so....
A friend of mine fell madly in love with this girl... as soon as they met they became another Chang and Eng. They dated for 2 weeks, then my friend invited her home to meet his parents. She was nervous as hell for some unfounded reason, but my friend knew that his down-to-earth parents would alleviate her angst in no time. Apparently dinner went off mostly without a hitch, no awkward silences, inopportune comments, etc... finally my friend's girlfriend asked to excuse herself. She was directed to the powder room which she judged to be too close for comfort to the dining room where the family was gathered. For some reason, instead of curtesy flushing to mask the sound, she decided to hike herself up on the free-standing sink to pee instead. No sooner did she balance her hiney on it, when the thing collapsed, ripping from the wall and sending her pitching forward. She promptly bonked her head on the wall and fell into a heap, dazed and almost unconscious, with her panties around her ankles, and the sink, cracked in half, lying next to her. This was how the family found her when they busted open the door, moments later.
I don't know if I could go on living after something like that.
