This is one that folks in your line of work could wake up screaming from. The very last Disclave (DC SF convention) was in 1997. Some genius with a room at the hotel who wasn't even a con member decided that fun and easy BDSM would be to tie his girlfriend to the sprinkler head (to him, an unidentified "thingie") in their hotel room. Said sprinkler head proceeded to break. The resulting flood was of biblical proportions, according to friends of mine whose hotel room was somewhere directly under his. The hotel blamed the con, and Disclave's name became sufficiently mud that they were banned from every hotel around. End of Disclave. So if you ever hear fen making jokes about sprinkler heads, you'll know why.
