Ricky Gervais stopped by The Tonight Show Starring Jimmy Fallon on Tuesday night to play a round of Lip Flip, and he soon had the host cracking up with his raunchy antics. As the name suggests, the two swapped mouths, with both — for some odd reason — adopting Southern accents in order to speak like the other comic. However, after Jimmy made Ricky call himself a "little baby," Ricky pulled out the big guns by telling "the absolute truth" about Jimmy's personal grooming habits.
