Bill O'Reilly and David Letterman high five after finally agreeing on something

bill-letterman-high-five.jpgThings that make you go "Hmmm." After years of general antagonism, Bill O'Reilly and David Letterman have come to an agreement on one thing: The U.S. should not have invaded Iraq.

"I think that was something that should not have happened in hindsight, but I will say that I supported it, going in, and I think we discussed this on your program way back when," O'Reilly tells Letterman. "Because all the reportage was that Saddam Huissein did have these weapons, and the weapons could've been easily handed off. Turned out that was not true."

Cue David Letterman doing a weird, Tom-Cruise-on-Oprah leap out of his chair and demanding a high five from "Billy." It's just super weird, and you need to watch it for yourselves.

"I'm not high-fiving you on a war!" O'Reilly says.

"It's just because we're feeling good and happy to see each other!" Letterman insists.
