Are you ready for the raunchiest, most inappropriate-yet-hilarious father/son comedy of the year? Adam Sandler and Andy Samberg are hoping so with Sandler's first-ever R-rated comedy, "That's My Boy."

MTV News premiered the film as part of our second annual Sneak Peek Week ahead of the 2012 MTV Movie Awards, and a slew of the film's stars were on hand to help present an exclusive clip to the lucky audience: Samberg, Vanilla Ice, Will Forte, Ciara, Milo Ventimiglia and Eva Amurri.

The film revolves around deadbeat dad Donny (Sandler), who got his teacher pregnant when he was just a teenager and raised his son Han Solo Berger (Samberg) as a single parent until Han turned 18. After a financial mishap, Donny reappears in Han's life on the eve of his wedding. As Donny tries desperately to reconnect with his son, who has changed his name to Todd, Donny must face the consequences of his terrible parenting.

The clip provides the background — or an explanation of sorts — for how teenage Donny ended up sleeping with his teacher. In a nutshell, the teacher started it. We see teenage Donny (Justin Weaver) sitting in what appears to be detention for writing an inappropriate note about his teacher (Amurri), who asks if he has a crush on her. Donny looks visibly uncomfortable with the question, particularly after she says, "So, you don't want me?" and takes her hair out of a ponytail and twirls it around her fingers.

"No!" says Donny. "Yeah? I don't know what I'm supposed to say right now!"

"Is that gum in your mouth, Donny?" she asks, putting her hand in front of Donny's mouth so he can spit the gum out, which naughty teacher puts into her mouth and begins to chew.

As is the case with many a Sandler comedy, the scene is both funny and gross at the same time.
