Chris Christie (R) said this morning that some of Gov. Jon Corzine's ads are "silly" and "beneath the office he holds." He also issued a New Jersey-style challenge to his opponent in next week's election relating to the subtle allusions to his personal girth seen in at least one spot.

"If you're going to do it, at least man up and say I'm fat," Christie told Don Imus on Fox Business Network. "Afterwards he wusses out and says, 'Oh no, no, I didn't mean that, I don't know what you're talking about.' Man up -- if you say I'm fat let's go, let's talk about it."

Here's the clip:

Christie jokes with Imus about his weight, saying he'll be a "big, fat winner" on Election Day. Asked how fat he is, he says, "Pretty fat, Don." Asked specifically about his weight, he says: "550 pounds." We think he was joking.
