I saw mark Hamill perform in a play once called Six dance lessons in six weeks. Rue Mclanahan from the Golden Girls played the female lead.
It was actually a really good play and I got to meet him during the opening night party afterwards. I was an idiot kid and asked him to sign the playbill with a MTFBWY or something dumb like that. He was visibly miffed, understandably, but still politely signed it "forcefully yours."
It wasn't until years later that I realized it was kind of rude of me to ask for that at the opening night party of a play he just worked really hard on. Must be real annoying having fanboys pestering you about a shitty movie you did decades ago. Anyway he seemed nice enough and it was a really good play. I got a pic with him around here somewhere, maybe I'll post if there's any interest.
