A number of the PM's have gotten me thinking. Who's the most famous person you've ever interacted with. Not just seen from across the street, but either chatted with or helped or worked with. The encounter can be one that lasted only a minute, but must have lasted more than five seconds.
I've got a couple, but I'll start with a classic actor. I got to meet and pre-interview Kirk Douglas. He had already been slowed by his stroke, but it was still very cool to help prep him and meet him. Very nice guy, much shorter than you would think given his movies.
