The dude you were sitting on must have been strong
funny story behind it too. my boys and i were at seaport village (a coastal shopping center designed to gouge tourists), and one of the stores there is a magic/joke shop. Well we loaded up on the stink bombs and hit the stalls all throughout Seaport Village. We put the little ampules under the toilet seats, so that when people sat down, the ampules cracked open. I don't think the three of us have ever laughed so friggin hard.
