I get some odd looks too. I don't know why, I guess some people can't except that I shave my head... or they don't think it looks good.
Sometimes I get them in class, particularly from underclassmen. I don't blame them, I was their age once(only 3 years ago).
the best looks are from guys at the bars and clubs when I snag a chick that they were gamin on. they are probably thinkin: "did I just get owned by a guy with no hair?"
