I was at my friend's apartment last weekend for a dinner, and I did #2 in the bathroom. Ten minutes later, my friend went to the bathroom, and it started to flood the bathroom! My two friends went to get the superintendent in their apartment building, leaving me alone in the apartment. I starting putting down towels in the bathroom, as the "water" from the toilet was nearly going out the room!

Suddenly, there was a knock at the door- it was my ex with his new girlfriend! He said he was visiting my friend. Needless to say, I did not let him in, but merely said she was "taking a walk." An hour later, my friend comes back with the super, and the super fixes the toilet. On his way out, he points at me and goes "she did it!" right in front of my friends!
