I recall reading in a book written by some retired airline captain that they had a landing contest on one flight. The deal was that if the pilot could land the plane and taxi back to the gate without causing the toilet seats to drop (they were placed in the up position by the flight attendants prior to landing), they would receive BJ's.
The crew managed to land the plane nice and smoothly, and all went well up until they taxied up to the gate. Just as they were pulling up the ground crew suddenly made a gesture with the batons to stop abruptly for some reason (I forget what). You guessed it, the seats all at once came crashing down, making a loud thump throughout the cabin. Needless to say, they lost the bet!
