I had a friend named Grover in highschool.. the only "teasing" as such that he got was that people assumed it was a nickname and not actually his real name, so they would ask his name and he would say Grover and then there would be silence and .. "No really, whats your name?????"
That's a point. I did a group course thing with a girl called Buffy once. When the instructor asked her name and she said Buffy she laughed then said "no really, what's your name?". It was so embarrassing.

Great to hear a Grover story in real life!
