"Jizz in My Pants" (known in the edited version as "J*** in My Pants") is a SNL Digital Short which aired on Saturday Night Live on December 6, 2008 and YouTube on the same day. It serves as the music video for the first single from The Lonely Island's debut album, Incredibad. The video stars The Lonely Island members Andy Samberg, Jorma Taccone and, briefly, Akiva Schaffer, and also features guest appearances by Justin Timberlake (who had also appeared in "Dick in a Box"), Molly Sims and Jamie-Lynn Sigler. "Jizz in My Pants" has been viewed over 150 million times on YouTube, as of April 2015, outviewing OK Go's popular treadmill music video, "Here It Goes Again", in less than six months.

The video's availability on YouTube is due to its publishing by The Lonely Island (and later Universal Republic in an edited version) instead of Saturday Night Live. SNL had previously posted its own videos on YouTube, but removed its channel when Hulu.com was created.

The singing is done in soft British RP style accents in the style of the Pet Shop Boys and their song "West End Girls", with Samberg additionally comparing the beat to the works of producer Timbaland. The video opens with Samberg in a night club singing as he is about to hit on a girl (Molly Sims). They head to her apartment, but as they share a kiss in the hallway outside her door he "jizzes" prematurely. He refuses to apologize, saying it would be "absurd" and blames the girl for overstimulating him by touching his , before he goes home "and change[s]". Taccone is then shown in a grocery store (where Justin Timberlake makes a cameo appearance as a janitor) conversing with a check-out girl (Jamie-Lynn Sigler), but jizzes in his pants as well when she asks, "Cash or credit?" After explaining that the way she bags cans got him "bothered and hot", he tells her that he will pay by check.
