One day, I heard that some guys on the third floor (IIRC) were pranking people by constantly pressing the elevator buttons, so that the elevators would always stop on the third floor, and they had a hose rigged up so that when the elevator doors opened, they would spray whoever was inside with water. Well, hey, that sounded like a lot of fun! I wanted in on that action!
So I went to my room, got undressed, put on a swimsuit, wrapped myself in a towel, took my room key and got in the elevator. The first thing the elevator did was, um, go to the first floor. That was a bit embarrassing, but some people knew about the guys with the water hose and they knew what I was up to.
Finally, the elevator went to the third floor and opened. There were the guys with the water hose. They saw me standing there, wrapped in my towel, and... didn't spray me!
One of 'em said, "What are you doing?"
I said, "Aren't you going to spray me?"
They looked confused. Then the elevator doors closed. I went back to my room, thinking, well that was a lotta nothin'. But then I realized, I'd come up with a clever way not to get sprayed!
