Uncle Joey and His Penis Once Pranked 'Full House' Co-Star John Stamos

Imagining Full House and its fictional family as anything else other than squeaky-clean has become easier in recent years with Full House patriarch Bob Saget rubbing away the last of Danny Tanner. (Before Fuller House existed.) But then there's Dave Coulier's Uncle Joey whose biggest scandal to date was the time Alanis Morisette allegedly did some NSFW things to him in a movie theater. In a Reddit AMA today Coulier revealed that theater thing wasn't even true, but did share another NSFW story which was a prank he played on John Stamos once. Spoiler: It involved his penis.

Coulier participated in the Ask Me Anything to promote Fuller House—which Netflix picked up for a second season—and a musical storybook featuring some of his co-stars reportsUproxx. Someone asked Coulier what was the best prank he's ever pulled on Bob Saget or John Stamos? That's when Coulier went into the NSFW story, while still being Uncle Joey about it and referring to his penis as "weiner."
