"Late Show" host David Letterman took aim at demonstrators outside his New York studio last night with humor.

Letterman was criticized by Sarah Palin for making a joke about one of her daughters but he later apologized and acknowledged the joke went too far. But a small group of protesters who want the talk show host fired gathered Tuesday outside Letterman's Times Square studio as his show was being taped.

In response, Letterman unveiled his "Top Ten Things Overheard At The 'Fire David Letterman' Rally."

Number 10: "David who?"

Number 9: "Well, it was nice of CBS to provide the catering"

Number 8: "We should have done this years ago"

Number 7: "What idiot turned Broadway into a pedestrian mall?"

Number 6: "Isn't there always a crowd demanding Letterman be fired?"

Number 5: "March around the potholes, people"

Number 4: "Can we also get CBS to bring back 'Gunsmoke'?"

Number 3: "When does Cheney get here with the waterboarding gear?"

Number 2: "He should apologize for that hairpiece"

Number 1: "Thanks for coming, Regis"
