urx unit loader The Lonely Island 'Go Kindergarten' in new music video with Paul Rudd, Sean Combs   Watch here

The day their third studio album, “The Wack Album,” was released, The Lonely Island also dropped a brand-new music video for one of the tracks, “Go Kindergarten.”

In the hysterical (and completely NSFW) video, surprise guest stars Paul Rudd and Sean “P. Diddy” Combs are out for a night at the club, when the guys (Andy Samberg, Jorma Taccone, Akiva Schaffer) are joined by Robyn to whip the crowd into a trance.

Without revealing much of the lyrics (because that would totally ruin the WTF-ness of the song), we’ll just say that the track mocks hip-hop’s penchant for demanding club-goers party as the song dictates.

Be sure to watch the video above, but don’t say we didn’t warn you about its NSFW nature.
