Ricky Gervais dropped by The Tonight Show Monday and was lucky to have the opportunity to play “Word Sneak,” a game that requires players to seamlessly slip in five secret words. The goal is to keep the other player from knowing what your words are, but of course, the game usually just devolves into a fit of giggles. (See: Bryan Cranston playing the same game last month.)

One of the words on Gervais’s list is gerbil, so he references an old urban legend involving Richard Gere and some inappropriate gerbil-related activities. Fallon doesn’t seem to catch this reference, but Questlove sure does.

Anyway, enjoy the cacophony of laughter as Gervais and Fallon hilariously stumble through the conversation.
