I have a terrible story that just happened to me. I went into the bathroom, sure enough the damn paper towel was in there. I push it open and sit on the bowl. I decide to give a courtesy flush and everything is going just fine, however I noticed the running water into the bowel is taking a bit longer than it usually does. It was about then I felt the cold water touch my balls and I jumped up. There is water flying out of this toilet like a canon, my pants are soaked, shoes soaked, I ran out of the stall with my pants down and jumped into another one.
I think I was booby-trapped.
