Jack Black, lol

Seriously though as far as movie actors go, um him, Billy Crystal, Kevin Spacey.

As far as actresses I don't think I really have any unusual ones except the ones everyone likes are overrated, like Megan Fox or Angelina. ScarJo or something like her but less blonde are where it's at.

Musically though, definitely John Lennon, hands down. Paul was never the cute one, though Matt can dress up like him in the later Beatles years quite well and make me change my mind.
