Poll: Have you met anybody famous? Were they mean or nice?

My sister met Diane Keaton on our trip to Hollywood YEARS ago and said she was a *****. She met Jean Simmons and his son and said they were strange. My family and I are going to CA and might meet Charles Shaughnessy, the man who played Mr. Sheffield (long story) and I am SYKED because The Nanny is my favorite show! Anyway, have you met anyone famous and were they or were they not nice?
