Guest Eliot Spitzer -- who's leading in the polls after tossing his hat in the ring hoping for a return to politics as a contender for NYC comptroller -- was asked by comedy host Stephen Colbert if forgiving voters signals the "slow decay of our moral values."

While Spitzer laughed the question off, Colbert declared, "This ain't Charlie Rose, motherf**ker!"

"Shouldn't the job of comptroller go to someone who has shown a modicum of self-comptrol," Colbert continued. "Why should the people trust you?"

Spitzer suggested that "The totality of a record," including his many years as New York attorney general, make him a suitable candidate.

Luckily, Spitzer seems to have a good sense of humor, as nothing was off-limits for Mr. Colbert on Thursday night.
