It's funny, but, time and again, I've found that if you genuinely don't care what people think then they will leave you alone, whereas if you show even slight nervousness about anything they will pick up on it and bully you mercilessly.
Friendly tip: Doesn't work if you're in the front row at a standup comedy club for the late saturday night show. (I still had a great time, but man, he just wouldn't let it go.)
Other than that, yeah, I totally agree.
As for the original question, no, not really. My high school was very clique-y, and while I'm sure I was occasionally made fun of by some, nobody ever really made fun of it to my face.
