I was called Sammy in college for four years because my roommate's friend decided to call me that and I never objected. I never talked much when I played pool at the student union and he was always there. There were some people who never knew in 4 years that my name wasn't Sammy. One guy even gave me a fake last name.
Just call me Sammy Knight
I get called "hippy" and "cut your damn hair" a lot.
