A professor at a Kansas university who dropped his pants and mooned a room full of students and teachers is under investigation after video of the incident was posted on YouTube, school officials said.

"We're sure that there's probably some facts and information that's just not available. I mean, you see a lot on the video, but we need to make sure everything is revealed before we take any action," said Fort Hays provost Larry Gould.

Sounds like everything has already been revealed, Larry.
