Republican presidential hopeful Mitt Romney managed to rip on Fred Thompson's late arrival to the campaign, his debate debut and his career as a "Law and Order" character all in one zinger of a joke.

Romney used his final remarks in the CNBC Republican debate Tuesday night to tell the audience, "You know I've come to know these people now over these debates. Is this our sixth debate, I think?"

Debate moderator Chris Mathews tried to block for Thompson, but Romney couldn't be silenced. Encouraged by laughing from the audience, he went on to say, "It's a lot like 'Law and Order,' Senator. It has a huge cast, the series seems to go on forever, and Fred Thompson shows up at the end."

Thompson chuckled off the joke, nodding his head and saying, "not bad, not bad. And to think, I thought I was going to be the best actor on the stage."
