Without fail, when I give my last name and add "with an X", I'm asked if I'm related to Jimi. I stopped being annoyed by it years ago and usually have something smart mouthed to say in return. I've caught myself doing it to other people so I'm just as guilty repeating the obvious question that very tall people get.
I *have* asked a urinal about it's superpowers, but I was impaired at the time.
