Jean Grey, Dracula & More Minor Celebs

So, I'm at Hart dog park on De Longore last Thursday evening. The crew is somewhat smaller than normal, but there is this really talk chick in big dark glasses, hovering over in the back corner. She’s acting a tad shady, but there's something strangely familiar about her. As I get closer and proceed with the normal nonchalant "Heh!" I suddenly realize that I’m talking to an X-Men! Famke Janssen, telepath Jean Grey in the movies, is making doggie small talk with me. Her Boston Terrier, Licorice, takes a liking to me and Bentley, we play stick, and all the while I so totally want to gush, to just acknowledge who she is, and say I loved her as Ava in Nip/Tuck.

So, we're all standling around, watching the pups, and out of the Hart house trundles Oscar Winner, Martin Landau - the guy from Space 1999 for god's sake! Now, I'm floored and pretty damn star struck, but Bentley, naturally, bounds into the house, passed Martin, forcing me to barge passed everyone and shoo him out. "Good dog," says Martin, "He knows 'out'."

So my question of the day is: What is the proper etiquette with these people? Do you pretend not to know them and just talk small talk? Do you gush and feed their egos with how good they are in this or that? Do we ask the hot guy at the gym if that was him in the Diet Pepsi: Ladies Man ad with Cindy Crawford (Brian is convinced it is!)? Should I ask Colton Ford to sign Brian's copy of Bearing Leather the next time I see him at Gold's?
