Bill O'Reilly melts down on live TV. The Fox News host really lost it with liberal radio host Alan Colmes, slamming the desk. The argument was over the federal budget cuts.

O'Reilly said, "Hold it. Hold it! Now, I'm getting teed off at you." and slammed his hand on his desk.

"You're lying," said O'Reilly.

Colmes responded, "I'm not lying."

"You are lying here!" O'Reilly persisted.

"Don't you sit there and call me a liar," Colmes said.

O'Reilly kept on going, saying "No, you're lying. It's jack what you're saying. There's another word for it but its obscene.This is just bull blank. You're wasting our time! This is bull blank!"

After nearly 10 minutes, O'Reilly regained his composure, asking, "Did I go overboard there?"
