Fox News anchor Chris Wallace hammered Vice President Joe Biden's excessive smiling and laughing during the debate, saying that he's never seen anyone be so disrespectful in a presidential or vice presidential debate.

And Wallace said that he'd seen most of them — all but the first four in 1960. He called his demeanor "unprecedented."

"I don't believe I've ever seen a debate in which one participant was as openly disrespectful of the other as Biden was to Paul Ryan tonight," Wallace said.

He added: "It was openly contemptuous and disrespectful."
