Jimmy Fallon's "lip flip" game is back with comedian and actor Adam Sandler.

Sandler appeared on Monday's episode of The Tonight Show with Fallon's mouth on his face.

He proceeded to then give an incredibly crass reason for how Fallon's hand got injured.

Fallon paid Sandler back by imitating the comedian singing a rendition of "All the Girls I've Loved Before."
