I'm pretty sure I have undiagnosed ADD, so my answer to this question really depends on what movies/TV shows I've watched/thought about recently. Remember on ER, how Lucy had ADD? And Carter was all, "why are you taking Ritalin, aren't you like old?" and Lucy was like, "eff you, GUY, you're going to get addicted to painkillers soon." Because he did. He got addicted to painkillers because David Krumholtz went nuts and stabbed him and also Lucy and he pretty much watched Lucy die right in front of him, because everyone else was down the hall having a Valentine's Day party. Why do I remember all of this? I don't know. So Carter survives but gets addicted to painkillers, sort of like Rush Limbaugh except skinnier and slightly less annoying. Then he dated Abby, who traded Kovac for Carter (um, OK, crazy, were you drunk?) and Carter totally judged her all the time for being an alcoholic but HELLO CARTER you were addicted to drugs, jerk. Then he decided to move to Africa because of all of his white liberal rich person guilt and dumped Abby in a letter. I think she was better off but I don't remember because I stopped watching after Romano got crushed by a helicopter, maybe the same helicopter that chopped off his arm. Stupid show. Anyway...thus explaineth this list:
Because Marshall reminds me of Joe (which I realize is a completely pointless use of one of my freebies but WHATEVER). And! Because he's hilarious. Because he's tall. And because he knows how important Muppets are.
But only if he's wearing Inceptionish wardrobe.
Nathan Fillion (aka Captain Tightpants)
But only if he's wearing his Firefly wardrobe.
Tennant, Eccleston, Smith (in that order)...I don't care. Yes, I do. Tennant. In his Doctor wardrobe.
Robert Downey, Jr
I don't care what he's wearing as long as it's nothing. BOOM! NAILED IT.
