This isn’t my moment, so I don’t know if this counts, but I was involved.
I used to work for a guy who had the only catalog of contemporary radio theater in the U.S. (I have so many crazy stories). He was, to put it mildly, a person with many problems and a bit of a celebrity fetish which was not helped by the fact that it was a point in the late 90s/Early 00s when audiobooks were getting big and famous people were getting into the idea of doing radio drama.
So we started carrying Alien Voices radio dramas. They were produced and starring Leonard Nimoy and John DeLancie (amongst others). They’re also not very good in my opinion, but that’s neither here nor there.
Anyway, he gets word somehow that Leonard Nimoy is going to be in Chicago and tells me that he and I will be going up there, a 5-hour drive, to meet him. I’m thinking this must be a business meeting or something. So we’re driving up there and he keeps building things up more and more, talking about “when we see Leonard” as if they were friends… it even became “Lenny” eventually.
Finally, we get there… to a mall. And inside the mall is a mall bookstore like they had at the time, maybe a Waldenbooks. And there’s a sign up that he’s having a book signing. Things are starting to seem weird. So he has us just get in line with all the fans and things are getting weirder.
Finally, we get up to the table, and my boss introduces himself and says who he works for. Nimoy looks at him with a look that he almost certainly gives to fans when they say things to him and he has no idea what they’re talking about and we both shake his hand and leave.
Then drive another five hours home.
And that’s the day I got paid to drive ten hours round trip to shake Leonard Nimoy’s hand.
Later I got to shake John DeLancie’s hand for the same reason, but under circumstances where things had been explained to him. Not much conversation there because he had a bad cold… and then I spent the rest of my time at that convention hoping I wouldn’t catch John DeLancie’s cold.
I honestly could write a book about working for that guy with all the crazy stories I have.
Edit: By the way, this is the very short version of that story.
