Gov. Corzine Ad Plays on Challenger's Weight

A television ad for Gov. Jon S. Corzine shows his hefty challenger, Christopher J. Christie, stepping out of an S.U.V. in extreme slow motion, while the narrator says that Mr. Christie "threw his weight around" to avoid getting traffic tickets. In a phone call to Corzine, Christie admitted he did throw his weight around, adding "on your mother."
