Ok, real celebrities that I’ve seen out and about (I don’t think that’s the actual point of this thread, but what the hey):
Jonathan Frakes and his wife (Jeanie Francis?) in a London pub sharing a drink and a quiet moment. I’m fairly sure I was the only one in there who knew who he was, and I didn’t know who she was until my wife told me later and I googled her name.
Richard Belzer getting take out in Baltimore.
Elliot Gould walking down the street in Cincinnati.
Jay Leno driving his old motorcycle (maybe an Indian) to the Comedy Store in Hollywood. He was greeting everyone waiting on line like an old friend. This was way before he had his own late night show.
Joelly Richardson (from 101 Dalmations and other films). I asked her out. She was in 10th grade when I was a senior at high school. She shot me down cold (how was I to know she was the daughter of famous people? I thought she was just some underclassmen with a Brit accent).
Corey Dillon eating a steak with what I have to assume was his nephew or some other young relative at The Precinct in Cincinnati.
Charles S. Dutton walking along the Inner Harbor on a nice, sunny spring day in Baltimore. He had two young girls with him, one on each arm. It was not that crowded that day and we were filming a video for work so I got him to say “hi” on camera with the two girls still on his arm. Don’t have that video anymore, as far as I know, so he’s past the statute of limitations.
Paul O’Neill, former Red and Yankee, eating dinner at Daveed’s in Cincinnati with a friend and their dates. They were at the next table and my wife has a huge crush on him, but we didn’t say hello or anything. I don’t like to bother folks just because they’re famous.
Sat next to Cris Collinsworth once on a flight from Cincinnati to NYC. We didn’t talk, even though we’re both Florida alum.
Had the above Collinsworth and Boomer Esaiason cut in front of us in line once at a Cincy pizza place. I was more annoyed than excited.
Talked to Pat Borders once before an Oriole’s v Blue Jays game. This was, IIRC, about a year or so before he won the World Series MVP. My wife grew up his hometown and that’s why he even gave me the time of day. They used to go trick-or-treating together.
I’m sure there are a couple of more that I don’t recall. It’s really not a big freakin’ deal, and none of these people is all that important or probably all that interesting to talk to, anymore than anyone here.
