I was gonna drop out, I even skipped posting the low talker from Seinfeld...
But I was just reminded of my calculus prof - PhD from India or Pakistan or somewhere along the sand belt.
I couldn't understand him for money. Plus that high pitched and uptone at the end of sentences. I recall him breaking chalk on the board trying to get his point across. If he had learned to speak English a little better it would have saved money on chalk.
Best part of it was he was also the advanced calc prof (nachully) - so I had him two semesters in a row.
