Too bad, it's just a nightmare.
We had something similar. It was a New Year's disco, and as a surprise, a guy and a girl in Santa Claus and Snow Maiden costumes jumped onto the stage in the middle of the disco. They started doing a striptease, right in front of our history teacher, who was quite shocked.
Believe me, it's a pretty common and not terrible sight. I'm quite good at it.
I think I've shaken all my vertebrae with this :D
