Chris Matthews escalated his mockery of Mitt Romney on Monday's "Morning Joe."
Romney was roughed up a bit during Sunday morning's GOP debate in New Hampshire, and Matthews seemed to love every minute of it. He said that Jon Huntsman's reproach to Romney for criticizing his serving under Barack Obama was the "magic moment" of the entire 2012 campaign.
"I have no idea what he believes," he said of Romney. "He's dog-trained himself to say certain things...he learns these sort of dog tricks!"
Joe Scarborough and Mika Brzezinski both started laughing at this comparison of Romney to a dog. Matthews was on a roll, though, and just kept going. He said that Huntsman's and Newt Gingrich's attacks on Romney were like the "Revenge of the Nerds." Then, he started mocking "the mom jeans, or whatever [Romney] wears." By this point, Brzezinski was almost shrieking.
"Stop it right now!" she said. "What is that costume he wears?" Matthews continued. "Nobody wears those clothes!"
"Terrible!" Brzezinski said.WATCH:
