The Whose Line Boys (2003): Colin Mochrie, Brad Sherwood and Chip Esten, regulars on the improv show "Whose Line Is It, Anyway?" were performing up at CMU while I was a student there.  I furiously scribbled this caricature in my car outside the theatre, met the guys after the show and got them to autograph it.  It doesn't get much cooler than that.  Created in Sharpee marker and colored in Photoshop.
