I've probably listened to Adam Samberg's "I'm on a Boat" (featuring T-Pain) seventeen times this week.
This from the Lonely Island (Samberg, Akiva Schaffer, and Jorma Taccone) debut album "INCREDIBAD", which may cause you to bust a gut. Repeatedly.
While this is the "clean" version (I have kids with negligent parents who let them visit my site), it's still not for the virgin-eared. The uncensored album version is available here.
