Bryan Cranston doesn’t know what a badonkadonk is.

The Breaking Bad star, who’s currently playing President Lyndon Johnson in Broadway play “All the Way,” went on The Tonight Show Monday and played a game of “Word Sneak” with Jimmy Fallon. Each one was challenged to sneak five words into conversation — including “badonkadonk,” a term that Cranston butchered before turning to the audience and mouthing, “I don’t know what that is!”

Watch the video below to see Fallon make fun of Cranston, and to watch the two of them giggle uncontrollably together. Warning: it’s adorable.
