The "Jizz in my Pants" video is just epic.
The wikipedia synopsis of the video is almost as epic:
"The video opens with Samberg in a night club and he sings about hitting on Molly Sims. They head to her apartment, but as they share a kiss in the hallway outside her door he ejaculates, or " jizzes," prematurely. Taccone is then shown conversing with a check-out girl, Jamie-Lynn Sigler, in a grocery store, but jizzes in his pants as well. When he calls for a cleanup, the janitor is shown to be Justin Timberlake. Samberg then exits a movie theater, when the discovery of a missed telephone call from a girl causes him to prematurely ejaculate. In another scene, Taccone is seen driving his car while listening to the radio, when a song begins to play that reminds him of a girl, causing him to "jizz in [his] pants" yet again. Samberg and Taccone then sing about how easily they "jizz in [their] pants" from stimuli such as an alarm clock, opening a window, the truth about Bruce Willis's character (Dr. Malcolm Crowe) in The Sixth Sense, and simply eating a grape. They explain that whenever they are adjacent to women, they ejaculate prematurely, which, they say, necessitates the constant wearing of condoms. Akiva Schaffer can be seen in the background at various times as the disc jockey.[3]"
