Late Show with David Letterman

Genius Grants; the U.S. Postal Service; a Top Ten List; and a Mitt Romney on the Late Show Simulation. TOP TEN: THINGS OVERHEARD WHEN JUSTIN BIEBER URPED To allay any concerns the Romney campaign may have, we decided to offer this simulation of how his appearance would go. Mr. Short is full of compliments for Dave, impressed with Dave's youthful hair and skin . . . the skin not firm, but very youthful. Kat, short for Katherine, is from the hit CBS comedy series, "2 Broke Girls."
