Let's get the bias declaration out of the way. I like Obama, I dislike Jay Leno. There, it's out there, now let's move on.
Last night, at the 2010 White House Correspondents Association Dinner in Washington, D.C., President Obama was very funny. He's been very funny before. In this clip, you can watch Obama's routine followed by Jay Leno's routine at the 17-minute mark.
There's no comparison. Obama killed, Leno wilted.
