I've had total strangers who are tourists ask to have their picture taken with me on two occasions, but I never knew if it was because they thought I was a celebrity, or they thought I was ridiculous, or they thought I was just irrestible and handsome (hey, they were always young ladies, iunno). There was a brief time in High School where people told me I reminded them of Quentin Tarantino, but luckily I was never mistaken for the man.
