The air before the game against the New York Giants and Philadelphia Eagles wasn’t the only thing chilly tonight.

The banter between anchor Bob Costas and analyst Rodney Harrison was biting, too.

Harrison began by making light of Costas’ black fedora hat during coverage on the NFL Network.

“That hat is not a Merry Christmas hat,” Harrison said.

Costas immediately launched into a defense of it.

“You are the only dissenter,” Costas declared, adding the 60,000 fans yet to arrive would agree with him.

“All I can say is, every time I look at you, instead of your false teeth, I see your hat!” Harrison retorted.

“The teeth are mine and I own the hat too!” Costas shot back.

“So now you’re 0-2! Don’t press your luck! You’re on a losing streak worse than the Eagles,” he said before turning back to the camera to read a prepared text.
