It was a battle of the lips — and SNL alums — when Adam Sandler stopped by The Tonight Show to promote his new movie, Pixels. Bored with Jimmy Fallon’s interview, Sandler decided to flip the tables and interview the host himself by participating in a fun game of “Lip Flip.”

While Fallon tried to help Sandler promote his film, the comedian managed to get in a jab about Fallon’s injured hand in a way that wasn’t entirely safe for work. “That’s what I get for trying it with my left hand,” Sandler joked, causing Fallon to crack up.

Sandler continued to roast Fallon, mocking his hospital stay and talking about his sponge bath, before launching into a rendition of Willie Nelson’s “All The Girls I’ve Loved Before” … which Fallon gamely joined in to duet on.
