I fell asleep for a few seconds.

Once vomited in one. I don't like elevators.

I have a funny elevator story, but not really something I "did". I was at a hotel for a banquet and at night, my friend and I went to mix a drink in our rooms and then head back down to the common area. We saw two security guards walking down the hall in front of us. I had my camera around my neck, so we decided to take a picture of their backside. They saw the flash and turned around and laughed.
So, we get to the elevator around the corner, and there they were. We were feeling embarrassed when we all four got into the elevator. Then one of them says, "We are not really security, we're strippers." Our eyes widened and they laughed and said he was kidding, they really were security. And they really were because we kept seeing them the rest of the night. But it was refreshing to "meet" hotel security that did not act like they were secret service, with a pompous attitude.

Not really all that strange but when I was about 17, I was at the gym in the wet area....and true to form made eye contact with someone. Soon as we both got in the elevator we started kissing. I think in all that distraction, we thought the "up" button had been pressed, but it hadn't. We didn't move.

Danced to my headphones.
