Adam Sandler and Drew Barrymore sang a song for The Tonight Show (with Jimmy Fallon on guitar) about their repeated on-screen pairings and it was sort of cute.

The duo have appeared in three films—The Wedding Singer, 50 First Dates and Blended, their latest film (that they were appearing on the show to plug.) Maybe not quite as funny as some of the previous Fallon offerings, but still. Sandler and Barrymore singing a duet is serviceable, I guess.

"You are the Fred to my Ginger Rogers," sang Barrymore in the "Every Ten Years" song. "You're the Rob Ford to my crack cocaine," serenaded Sandler. "Am I your best movie husband...Better than Hugh Grant?"

"I will still love you when your boobs touch the floor," crooned Sandler. "So right now?" responded Barrymore. LOL LADIES' BOOBS GET SAGGY YOU GUYS. Oh well. At least we had that Rob Ford joke.

Also, this video reminded me that Fallon and Barrymore were once in a movie together, which I had totally forgotten about.
