As our own Jason Linkins pointed out, Letterman is one of the few comedians who needn't mourn Sarah Palin's passing off stage. After their feud this year, Letterman ended up apologizing (twice) and Palin became a touchy subject on his show for the weeks after. Now that she's resigned Dave is back in full Palin-joke form.
Monday night he spent the bulk of his monologue mocking her and last night he did a Sarah Palin top ten (without calling her a slutty flight attendant). In last night's list he managed to mock John McCain, George Bush, and himself all the while lancing Palin and her decision to step down.
