We got so P*ssed off at our chemistry TA, Hong Ma, that we rioted in the classroom screaming at him: "What the F$%# are you saying!?" "What the F$#% are you saying?".
We caused so much trouble that he ran out of the room and got the prof. The prof ended up appologizing and getting us a new TA. It was pretty ugly.
Back when I was in grad school, there were a few times I had to ride to the rescue of a foreign-born TA... That irritated my advisor to no end, because, of course, I was supposed to be working!
LOL! Yeah, I had a calculus TA like that - for years afterward I pronounced it "parabora" and "hyperbora" and giggled. Thing is, though, once you cut through the accent she was one heckuva math teacher. She had to be to beat it into my cranium...
