My co-workers call me Tiger. as in Tiger Woods. People also say I look like Pharrell. What's funny is I AM NOT BLACK.
At this instant: aiming for George Harrison circa the White Album (without the mustache), but closer to Rather Dashing from the live-action Peasant's Quest At various other times: Andy Roddick (although I've never had the physique), Ashton Kutcher (especially in the early years of That '70s Show), Timothy McVeigh (when I've got a buzz cut), Kevin McHale (less 7 to 20 inches) Dishonorable mention: Helen Hunt (a *really* bad student ID picture)
I wished I looked like Bolo. That has to be one of the most awesome resemblances ever. The one I get most consistently is Howie D from the Backstreet Boys: During the one year I had long hair, I was told I looked like Johnny Depp a few times. Howie D is definitely the most common one, though.
