Watch: Ricky Gervais Flips Lips with Jimmy Fallon, Talks Ball Shaving (Yep)

Watch Gwen Stefani, Blake Shelton & Jimmy Fallon face off.
Last night it was Ricky Gervais’ turn to flip lips with Jimmy Fallon on The Tonight Show.

But unlike previous lip flip sessions, this one took a hard turn to TMI territory when Gervais brought up ball shaving. Really.

Now believe what you want, but just look at how Fallon’s eyes begin to tear up when Gervais announces the “absolute gospel truth.”

The duo also executed a pretty neat rendition of “Little Drummer Boy,” because it’s almost Christmas.

Watch it all go down, above.

Gervais’ next film, Night at the Museum: Secret of the Tomb, opens Dec. 19.
