Time again to remind you of life's most trustworthy truisms: 1) David Letterman is -- and always will be -- the king of late night, and 2) Jim Carrey is not just an A-List movie star, but perhaps the single greatest talk show guest of the past 20 years. Even when he's accused of "plagiarism," he shoots his pupils around, juts his jaw like an angered Katharine Hepburn, and comes out on top.
Oh, we all copy Tom Hanks sometimes, right? Hard not to pilfer a bit from the man who gave us Punchline.
