It hasn't been a good week for David Letterman, but when he's not talking about affairs with staffers you remember that he's a pretty funny guy. A new segment called "Rush Limbaugh, Funnier Without Audio" where he scores video of the conservative talk show host with circus music is classic Letterman.

It turns out an hour wasn't enough for Pres. Obama's appearance on the Late Show With David Letterman. While the sprawling interview touched on everything from the president's kids to health care to the war in Afghanistan (if you missed it, you can watch it here), one thing got left out: Letterman's Top 10 list. Luckily CBS put the list, titled 'Top 10 Reasons Pres. Obama Agreed to Appear on the Late Show,' online as a Web exclusive. Our favorite was number 5: "We told him Megan Fox would be here."

Did you know that Dick Cheney hates it when you reveal the plot of "Gossip Girl" before he's had a chance to watch it? Also, don't call him Ricky. Apparently Condoleezza Rice called him Ricky once. Once.

A bikini-clad Britney Spears was on David Letterman last night to present the 'Top 10 Ways the Country Would be Different if Britney Spears Were President.' Shudder at the thought. The pop star did have some good ideas on foreign policy, however, such as only invading "fun places, like Cabo."

After David Letterman offered a mea culpa to then Alaska Gov. Sarah Palin for a somewhat tasteless joke he made about one of her daughters, we couldn't help but wonder whether the brouhaha would make Letterman gun shy about delivering future jokes at Palin's expense. Turns out it hasn't. Last Friday's Top 10 list offered a parting shot before Palin's official resignation from her governor's seat.

Former Illinois Gov. Rod Blagojevich continued his media barnstorm last night on the Late Show with David Letterman. The interview started off bad for Blagojevich (Dave: "Why exactly are you here, honest to God?" Blago: "I've been wanting to be on your show in the worst way for the longest time." Dave: "Well, you're on in the worst way, believe me.") and didn't get much better. Here's an excerpt:

Some people may not be sorry to see George Bush go, but David Letterman is. Letterman recently lamented that the departure of Bush left no choice but for his show to end its tribute to "Great Moments in Presidential Speeches" - what Letterman called a "heavily-laden vein of comedy" stretching back to 2006. All good things must come to an end.
