Ricky Gervais might just be Jimmy Fallon's best "Lip Flip" partner to date!

On Tuesday's Tonight Show, the Derek star and the late-night host swapped mouths (with a little help from technology, of course) and proceeded to interview each other. Jimmy decided the British comedian should speak as a Southerner schilling timeshares, while his guest did an impersonation of his own!

"Hi, I'm Jimmy Fallon—I got my own TV show," said Jimmy—well, said Ricky as Jimmy. "Yeah, I can't believe it neither! I come on and I sit down and I talk, and sometimes I sing, and other people talk, and when other people are talking I'm getting paid when they're talking! It's amazing! I'm getting paid now and someone else is doing all the entertaining!"

This prompted some giggles between the gentlemen, which led to a series of funny expressions on Ricky's face (thanks to Jimmy's lips!) and a proclamation of, "I'm a baby! I'm a wittle baby boy."

That didn't last long, though—Jimmy decided it was time for Ricky to put on a show. "You guys wanna see me vogue?" he asked, and the Office alum obliged—hand motions and all!

Soon it was Ricky's turn to do the talking again, and speaking as Jimmy, he took "Lip Flip" in a dirtier direction, saying, "I'm Jimmy Fallon...and, Jimmy Fallon don't lie, so what I'm gonna tell you now is the absolute gospel truth and I want you all to remember it whenever you think of the name Jimmy Fallon: I'm Jimmy Fallon, and I shave my balls!"

"Me, too," Jimmy (as Ricky) quipped!

The real Ricky's hand motions got a little, um, vulgar as he mimicked the action of shaving his nether regions.

This went on a few beats before the gentlemen launched into a surprisingly wholesome Christmas duet: "The Little Drummer Boy." Jimmy, in particular, was quite impressive with that one! Watch the clip above to see for yourself.
