Yesterday, at a thesis defense, I had difficulty seeing the whole screen.
Not because I was in the back.
Because one of the committee members had his feet propped up on the conference table (at the very front of the room!), blocking part of the screen.
I've seen a number of odd seminar behaviors demonstrated over the years, from the normal--falling asleep--to the not-so-normal--lifting up a butt check to really let one rip, but feet on a conference table? Sheesh.
What's the oddest thing you've seen a faculty member do, either in or out of seminar?
