You only get five. by Heather Hamilton, found via diveintomark.

And let me just take a moment to explain the Five Fame Fuckers list for those of you who don't already have one: if you're in a committed relationship, you're allowed to compile a list of five people you'd like to sleep with, but the people on the list not only have to be celebrities, they also have to be celebrities you don't know or wouldn't ever happen to bump into, even in the most remote social situation. To make things fair, the person you're in the committed relationship with gets to compile his/her own list. So, if you don't have one, please do us all a favor and get one.

Well, I'm not in a relationship, but if I were in one then my list would be: (in no particular order) Sarah Michelle-Gellar, Nicole Kidman, Alyson Hannigan, Katie Holmes, Kelly Macdonald.
