As a kid I was in the store with my parents and we were in line for the register. Some guy turned around and looked at me and said "Hey kid, ever seen a $2 bill before?" I said no, and he ripped off a $2 from a pad and handed it to me. To this day I have this $2 bill because I thought it was fake. This is the midwest, no way was this Woz but now I feel that this might not be a fake $2 bill anymore.
