President Barack Obama may be delivering a speech at this very moment to the troops in Afghanistan, but last night, one of his speechwriters was delivering jokes and winning Washington, D.C.'s annual "Funniest Celebrity" contest at the D.C. Improv.

Jon Lovett took the prize by impersonating Arianna Huffington for an impromptu Q&A with the audience, and making quips at the expense of Sarah Palin, Grover Norquist and the TSA. Related fun fact: Lovett has worked with head White House speechwriter Jon Favreau on each of Obama's humorous remarks for the White House Correspondents' Dinner.

Here is Lovett's full set, provided by Politico.


 

Congressman Rick Larsen (D-Wash.) finished runner-up, while Norquist took third place.
