Letterman Gets the Last 10 Laughs

"D avid who?" was the 10th most-overheard comment at yesterday afternoon's "Fire David Letterman Rally," the CBS late-night host joked last night on his "Late Show."

While the show was taping, a whopping dozen protesters held up banners outside Manhattan's Ed Sullivan Theater where "Late Show" tapes.

No. 9: Well, it was nice of CBS to provide the catering.

While the protest raged in miniature outside the theater, inside Letterman was reading the night's Top 10 list: Things Overheard at the Fire David Letterman Rally.

No. 8: We should have done this years ago.

The number of people who attended the rally outside swelled to around 40, according to MSNBC -- if you include all the news media recording the outrage, as well as tourists and rubberneckers joining in the fun.

No. 7: What idiot turned Broadway into a pedestrian mall?

The protest was staged in response to a joke Letterman made last week about one of the daughters of Alaska Gov. Sarah Palin being "knocked up" by Yankees third baseman Alex Rodriguez during the seventh inning of a game, when the Palins visited New York.

No. 6: Isn't there always a crowd demanding Letterman be fired?

Letterman tried to make light of the leaden joke in a kinda-apology last week after Palin called the joke "sexually perverted."

No. 5: March around the potholes, people.

Letterman insisted the reference had been to Palin's 18-year-old unwed-mom daughter, Bristol, not her 14-year-old daughter, Willow.
