Days before Andy Samberg's Lonely Island debut album, Incredibad, hits shelves on Tuesday, the boys behind SNL 's digital shorts released their new single "I'm On a Boat" as a digital short on Saturday Night Live. The clip features Samberg and pal Akiva Schaffer as they hit the open waters for a nautical joyride alongside hip-hop artist T-Pain. Brace yourselves, because they've  brought their swim trunks and "flippy-floppies." Oh, the things you find in the bottom of a cereal box.
