Oh, the mentality of physics teachers...
We were in class the other day, and he was trying to describe a problem about forces and the forces that were acting on this kid sitting on a swing. In speaking about the problem, heaven forbid he say anything about the kid's "butt." Well, he did (*gasp!*), and it freaks me out a little at how much he hesitated when he said it. What freaked me out more was that I was in a class full of people that were 20-years-old and up, and that people actually laughed when he said it.
Butt. Hilarious. *insert sarcasm here*
And the real kicker was that after saying such a horrendous word, my physics professor said, "Ya, go ahead and report that to the Honor Code office."
I can only wait until the day he decides to exclaim, "Oh crap!" when one of his demos go wrong or something.
