David Letterman and Conan O'Brien.
But Dave got a shave a week ago, so his YOB is over already. I don't know what the big redhead has in mind, but he most certainly does look like some kind of freakishly giant version of the Lucky Charms leprechaun.
As you steep yourself more in the YOB lore, it' surprising to find out how many notable men (a a few women, too, I guess) have sported a beard. For example:
President James A. Garfield
Celebrated actor, director and anti-Semite Mel Gibson
