John Stamos appeared on The Tonight Show with Jimmy Fallon Monday night to promote his upcoming show Fuller House.
But the pair ended up reliving their awkward first meeting at a Paul McCartney gig, when Stamos was a bit too eager to shake Fallon’s hand and instead, “fish-hooked” Fallon in the mouth with his finger.
“Your thumb went in my mouth,” Fallon said. “I know for a fact it happened.”
The host proceeded to show the Grandfathered star exactly how it happened by reenacting the scene — complete with a finger right in Stamos’s mouth.
