Guests of the Week: Feb. 2-6, 2009

Here are our picks for the guests who will be worth watching during the coming week. Feel free to weigh in if you have a guest to recommend. Though last week, which featured a last-minute addition of Paul McCartney to Wednesday's "Colbert Report," reminds us that everything is, of course, subject to change.

David Letterman welcomes Steve Martin, fresh off his "SNL" hosting stint, on Monday; he stops by "Live with Regis and Kelly" on Tuesday and "The Colbert Report" on Thursday. Good thing he's usually a funny guest, or this would be getting perilously close to overload. Tomorrow's "Late Night with Conan O'Brien" features the always hilarious Kathy Griffin. "Slumdog Millionaire"'s Dev Patel (love his real-life British accent!!!) will be on "The Daily Show" Tuesday night, while "TDS"'s Senior Black Correspondent, Larry Wilmore, takes a seat on "Jimmy Kimmel Live" on Friday. If you can't get enough of Neil deGrasse Tyson, he's scheduled to appear with Tavis Smiley on Thursday. And we love the strange-bedfellows aspect of Thursday's duo of guests on CBC's "The Hour": Former Prime Minister of Australia John Howard, and the co-star of numerous Kevin Smith comedies, Jason Mewes.

Don't Bother: We realize funny is a subjective thing, but Robin Williams, appearing on Tuesday's "Late Late Show with Craig Ferguson," always gives us the hives when he appears on a chat show. Dial it down a notch, Robin.

Pluggernaut of the Week: A tie between the stars of the upcoming comedies "He's Just Not That Into You" and "Pink Panther 2." Drew Barrymore, Jennifer Aniston, and even phrase-coiner Greg Behrendt will make numerous appearances, and co-star John Cleese will share "Panther" promotional duties with Martin, covering the West Coast while Steve handles the East.
