"Motherlover" SNL Digital Short

Five months after the events of "Dick in a Box," Samberg and Timberlake's characters (who have just been released from prison) sing about special gifts for Mother's Day, with Susan Sarandon and Patricia Clarkson appearing as their mothers.

They decide the best present for them would be for them to have sex with the other's mother. They proclaim it is the second best idea they have ever had. Music originally left off of sessions for the album Incredibad, as produced by Asa Taccone and Drew Campbell.

"We weren't sure if we should go in a whole different direction and make a new song that has nothing to do with those guys or a short film that's totally different...We didn't want to ruin the first one because it was so cool."”

— Akiva Schaffer

Schaffer said the stunt casting of the moms was relatively easy. Susan Sarandon's name popped up very early for the role of Samberg's mom. "We needed a blond actress who looked like Justin, and I don't know if I even told the other guys, but I was in a hotel room a week ago, and I turned on the TV and saw the movie 'No Reservations,' and Patricia Clarkson plays the restaurant owner in that," Schaffer said. "So, I brought her up, and they all said yes immediately." Both women were quick to sign up. Clarkson showed up on set at 11 a.m. on Friday, after just agreeing to the gig around 12:30 the night before.
