Michael wins the award for celebrity sightings... I'm very curious to see if any of the other LadyKillers can even come close to the variety and number of celebrities he's rubbed elbows with!
I can't even come close. In fact, I had to wrack my brain to come up with much of anyone. I guess living in the 'burbs doesn't lend itself to bumping into celebrities very often. However, I can think of three folks (or maybe two-and-a-half...) who might be classified as such.
When I was about 12 or so, my buddies and I were deep into our "spaghetti western" phase (or mania, depending on your POV). When we heard that Clint Eastwood (aka The Man with No Name) was coming to our neck of the woods for a celebrity golf tournament, well, we all decided we had to go..."in costume." (I wince a little in reporting this, but hey, we were 12.) What this meant is that we showed up at the golf tournament wearing serapes, Old West style hats, cowboy boots (if we had them), and so on. We trailed around after Eastwood, from hole to hole... I recall him throwing a few amused/puzzled glances along the way. Yeah, we were definitely fan-girls. I think we all got his autograph, but I can no longer recall.
In my work-a-day life, I met the physicist Edward Teller. Whether you regard him as famous or infamous is a matter of opinion, and I'm not about to go there. I did some editing for him... well, ostensibly for him. There were actually many layers of people between him and me, and I think after that initial meeting I didn't talk directly to him again.
On the other side of the coin (so to speak), I got to attend a fairly exclusive meeting in the historical abode of J. Robert Oppenheimer while he was at UC Berkeley (he lived on Eagle Hill, in Kensington), and write up an article about that event for the UC Berkeley Physics Department. Okay, so Oppenheimer wasn't there, but as I wandered about the place, looking at the view, marveling at the architecture... I tried to imagine what it was like when Oppenheimer, Ernest O. Lawrence, and the other glitterati of 1930s physics walked those tile floors.
Okay, so I didn't "sight" Oppenheimer, but between my imagination and just being on the premises, it seemed that all I needed to do to turn a corner and I might catch a glimpse of "Oppie" in his trademark porkpie hat, walking away...
