Dennis Miller’s song about Vladimir Putin’s nipples to the tune of “Puttin’ on the Ritz” was featured on The O’Reilly Factor’s “no spin zone" last night. Just another part of The Factor's mission of "looking out for you," apparently.

Miller visited The O'Reilly Factor for his regular Wednesday night gig of mean-spirited “humor.” In this one, Miller told some actually funny jokes about Starbucks' plan to have their baristas talk about race with customers. Then it was on to a completely un-funny bit about Al Gore literally re-enacting the Salem witch trials over climate change.

MILLER: Guys like Gore …they’ll burn you at the stake claiming you don’t believe in global warming. …He’s a bit of a dangerous cat. I think he’s loony enough, I think he would eventually make the call on what he feels the punishment should be and that’s creepy stuff.

Then things got weird.

O’Reilly switched gears to Putin's recent disappearance from public view. O’Reilly asked Miller, “What was he doing?” It was obviously a pre-arranged joke, because Miller said he had asked in advance for the graphic that appeared on the screen with Putin in a top hat and with mini top hats over his nipples.

“He was out of town in New Haven, opening up his new musical production that he’s taking to Broadway, called “Putin on the Ritz,” Miller said.

Miller began to sing:

When my nipples begin to tipple,

You will feel a tectonic ripple.

When the Balkans feel my mitts,

Putin on the Ritz.

“Come on, Billy!” Miller said. He began dancing in his seat as he re-sang the lyrics.

I kid you not.
