How come whenever a character throws a nutty, he is forced to grow a beard?
Roy Anderson, The Office (Arrested for DUI in aftermath of breakup with Pam.)
Jack Bristow, Alias (Imprisoned for doing something involving Irina Derevko. I think.)
Fox Mulder, The X-Files: I Want to Believe (Disillusioned with "the truth.")
And of course, Jack Shephard, Lost (Obsessed with "going back.")
Is it just because messy beards signify that these guys have been too preoccupied with being crazy to shave? Or do we associate (either literarily--yeah, that's not a word, but whatever--or in real life) beards with something sinister?
