Met? None, other than the occasional Playboy centerfold or model. :sneaky:
Seen? Same place as above, suddenly Hugh Hefner walks through, with his entourage. That man exists on a whole different plain of existence from the rest of us human beings. You can see it, but you'll probably never be lucky enough to exist in it.
Also, once, when I was a kid, the family was on vacation out west somewhere (Utah?), and suddenly came across a shitload of vehicles pulled off on the side of the road. Dad decided to stop and see what was happening, and we found out they were filming a scene from the 70's TV show, "Alias Smith and Jones". Got to watch them do take after take, as various modern day life kept intruding into their 19th century cowboy scene (jet noises overhead, someone's styrofoam cut bouncing across the scene, driven by the breeze, etc). Was a combination of interesting to watch, and yet excruciatingly boring, too!
