David Letterman to Herman Cain: Dial 9-9-9 for a Free Pizza

The late night host accuses Cain of not knowing what his own plan is

After his most recent gaffe in Milwaukee, Herman Cain refused to conduct an interview with the News Hampshire Union-Leader if there was going to be a camera in the room.

But that didn’t stop him from appearing on David Letterman Thursday night, where he received a roasting instead of a grilling.

When Cain brought up his 9-9-9 plan, Letterman was eager to pounce.

He told Cain, "But you don’t even know what it means. I heard somebody say to you “how would so-and-so and so-and-so be handled under 9-9-9?” and you said, “I don’t know!”

Cain claimed it was an "obscure" question, but Letterman seemed to think it was pretty simple.

"You dial 9-9-9 you get a free pizza."
