I have a friend who had a List like this with her GF, who also had a list.

Oh, ouch for your friend's ex-GF.

I think a key component of the List is (or ought to be) that the persons on it are totally improbable. My list contains Stephen Colbert, who is married with kids and devout and ethical and at the other end of the continent, and Seth Green, who is filthy stinkin' rich and a decade younger than me and before whom, if actual contact ever happened, I would be dead certain to make such a fannish ass of myself that he wouldn't touch me with a 10-foot pole (but he'd be all nice and polite about it, because that's how he is, which is why he's on my List).

My list emphatically does not contain That Cute Swashbuckler At Faire or That Sweet And Incredibly Gifted Local Actor I Kinda Know. Remotely real-world accessible=OFF THE LIST. This seems like a good safe rule.

Or anyone too international, like Isabella Rosellini.

Yeah, my list is people like George Clooney.

Boy has Tea Leoni and I have Nathan Fillion. That's pretty much it.

Or anyone too international, like Isabella Rosellini.

Heh. That one was on just recently.

Remotely real-world accessible=OFF THE LIST.

This rule works right up until the point where you find out that the man you are dating knows Eddie Izzard, as my sister once discovered.

Well, if George Clooney starts coming to Little League games, I'll take him off the list.

My friend worked in the music industry so came into contact with people on her List. Mistake the first. Notice also how I said "worked." It was an ugly and fascinating thing to witness. Her poor ex-GF. She was a sweet woman but ultimately the two were not well-matched.

My LIST:

Orlando Bloom
Hugh Jackman
Dominic Monaghan
Michael Shanks
Paul Gross

Hang on, my fandoms are showing.... tucks in petticoats

eta for formatting and because I forgot about Nathan Fillion OMG.

Yeah, my list is going under dramatic reconstruction if we get the film deal we're working on fir the building right now.
