Johnny Knoxville plants a playful smooch on "Watch What Happens Live" host Andy Cohen.

Lately, Johnny Knoxville's been making the talk show rounds to promote his new movie, "Bad Grandpa" (in theaters today!), and last night the stuntman stopped by Bravo's "Watch What Happens Live," where, much like it did on Jimmy Kimmel, the topic of Johnny's former MTV gig creeped its way into the conversation. Once a "Jackass," always a "Jackass."

In the clip from the show below, a viewer calls in to the clubhouse to ask the jokester about his first stunt ever. "Apparently at nine months old, I threw myself out of the crib constantly, and [my parents] had to, like, take me out of the crib," he answers. We imagine the poor folks of Johnny's fellow former child daredevil, Jolene Van Vugt, suffered through the same type of scenario...though at least they never had to see their daughter willingly get kicked in the nuts.

Watch the video for more from Johnny, including the identity of his celebrity man-crush, and check out MTV Movies Blog for more "Bad Grandpa" news.
