Funnyman Sandler took full advantage of the fact that he had control of Fallon's mouth during his appearance on The Tonight Show's always hilarious game segment, making light of his host's recent hand injury and taking the show to a whole new (smutty!) level.
"I'm Jimmy Fallon, look at me, I injured my hand whacking off," the 48-year-old actor said as he became Fallon's mouthpiece. As Fallon tried not to dissolve into hysterics, Sandler carried on. "It was so much fun. That's what I get for trying it with my left hand!"
Fallon then gave Sandler a taste of his own medicine but the Big Daddy star was already working on his comeback!
"Oh how I miss the hospital," Sandler's mouth continued, as the screen switched back to Fallon’s face. "I liked it when that old dude gave me a sponge bath," he added.
Sandler's cheeky comments continued as Fallon introduced a musical element to the bit, getting his guest to join in a sing-along of Willie Nelson's "All the Girls I've Loved Before."
Watch the video above to see the hilarious lyrics Sandler came up with for Fallon's moment in the musical limelight!
