It usually happens when I'm just walking around minding my own business & so are they. I never recognise them but realise I know their face, so usually I mumble "Oh hi - how are you?" Or something similar, thinking it would rude not to. This has happened with Yoko Ono in Brussels, Zoe Ball in a lift at Heathrow Airport, & Ross Kemp in Cairns, etc. They generally smile & we have a bit of a conversation. I then realise who they are & scuttle off. I would never go and specifically try to meet a "celebrity" - no interest at all!

Ron Paul I guess, pretty well known congressman from Texas.

Warren Oates who is now long dead.

I had a beer with Ian Anderson (Jethro Tull) in a bar in Schwabing (Munich) and i was introduced to Ravi Shankar in Amsterdam.

Prince Charles. I was a plasterer at the time and our workers co-operative had just completed making and fitting a set of windows in the building so we were invited ot a very select opening of the New Enterprise Workshop in Liverpool. Prince Charles had a lot of bodyguards roaming around and some of them were giving us really bad eyes - I think they were just upset that we were roaming around too so they couldnt really have kept him safe- At the end point there was to be a a demonstration for the Prince of a 'hilti gun' we were all lined up to greet him and one bodyguard was glaring at all of us in line and teh other bodyguard was with the prince who had his back to us - The building was really empty and echoey with nothing in it but concrete and steel and the hilti gun made a noise like a gunshot - the guard watching us went white and nearly wet himself and tried to jump backwards to take the shot. When the Prince shook each of our hands in turn he said a few words - to me the only woman there he said "You look very clean for a lady plasterer!"

Jerry Garcia of the Grateful Dead came to my window when I was a bank teller. At the time I wasn't familiar with who he was. I also helped CA Senator Barbara Boxer twice, one at the bank and once as a customer at Crate & Barrel where I worked at that time.

I have a long list, worked backstage at the Sunrise Musical Theater in the 80’s... I have a ton of stories, 1 highlight; Frank Zappa threw a giant rubber double ended dildo at me, and I threw it back.

Robert Redford while Backcountry skiing in Colorado. He stopped and asked about the weather up the trail.

Bill Clinton.

There have been so many over the years. Willie Nelson, Chet Atkins, Les Paul, John Wayne, Leon Russel,The Doobie Brothers, Lynyrd Skynyrd, Ron Howard, Mr. & Mrs. Knott (Knott's Berry Farm). There are many more. They're just people.

No one that I can think of, but then I am not inclined or interested. They might be Famous or infamous depending on your outlook, not so ?

Troy Baker, Tom Hiddleston, Elizabeth Olsen, Bill Murray, Harrison Ford, Zak Bagans, Vic Mignogna, Red Jumpsuit Apparatus, Avenged Sevenfold, three days grace ....all except troy and vic and the bands outside of pay to meets (conventions, signings, concerts, etc)

Harrison Ford visits wichita often and bill murray's brother lives in my work town and bill loves our golf course lol met Tom and Elizabeth on the set of 'I saw the light' in Shreveport, and Zak was doing filming in KC so I drove up and hung out

I don't consider my fellow humans in those terms. I just admire some peoples work, be they an actor, musician, artist or care worker.

I met Arlo Guthrie back in 1976 playing in a local bar in Connecticut. Really nice guy!

I met Peter Tork of the Monkees. I went to see his band The Shoe Suede Blues and got to meet the whole band. He told me I was cute!

The most famous? I met John Kerry at a rally in 2004 (he shook my hand and kissed my cheek), and I met and spoke to Dennis Quaid at a local bar when he was filming in my home town (Yuma, Az.). He called me "chere".....so very Cajun!!

As a New Yorker, I've SEEN a fair amount of famous people -- but was too shy to approach!

Leonardo Decaprio in Ralph's Supermarket checkout where I let him use my club card.

I’ve met Dolph Ziggler (WWE Star), TC Carson (Videogame Voice Actor best know for his role as Kratos), I’ve met the band members of Saliva and Puddle of Mud, and I’ve met Andy McNamara (Editor In Chief Of Game Informer magazine).

I mean, I’ve met a few others but these are the more famous ones off the top of my head.

Steven fry

George Carlin, backstage at the Ice House comedy club in Pasadena, CA, after a show.

And Jennifer Love Hewitt came into the camera store I used to work at many years ago. Still waitig for that autographed picture....

I was lucky to meet Richard Dawkins when he spoke at a convention in Honoulu a few years ago. Was very brief, but cool. I see a few celebrities here on Kauai, but don't interact with them. I've "married" several somewhat famous people, but I don't keep up all that well with celebrities, politicians, musicians and actors, so didn't always realize who they were until after. Probably the most interaction I've had is that I performed the marriage of the drummer for the Grateful Dead (Bill Kruetzmann) in his house here on Kauai, and read a poem he had written about a mango tree.

Either SECNAV Lehman or The Blue Man Group. The chance to see their props alone was worth the work, seriously incredible engineering mated to child-like imaginations. The fact that they survive touring makes it even more mind blowing.

Joe Biden. I shook his hand at a fundraising event back in the 90s.

I'm on "the other side of the table" at cons, so I've been around a lot. Most famous I've ever sat around and shot the shit with would have to be hanging out with Harlan Ellison and Peter Straub one afternoon. Before I got to the position where I could do that, and not counting anyone I met through my mother, I was Mark Leonard's temporary PA for a day. And I hung out with James Irwin for an hour or so.
