At the end of a long day I went into the bathroom alone to use the "sit-down" toilet (if you know what I mean). Someone had placed two pop-its (those paper popping things people throw on the ground on the 4th of July) under the knobs on the bottom of the toilet seat. As I sat down, completely vulnerable, I suddenly started to feel like I was falling (1 cm, but still) and simultaneously heard a loud popping noise. Let's just say it scared the crap out me. It did make laugh though. If it was you and you're here, well done.
