The Lonely Island & Jimmy Fallon Play 'I'm on a Boat' on Classroom Instruments: Watch

The Lonely Island brought some nautical swag to the Tonight Show Starring Jimmy Fallon on May 16, where they performed their 2009 smash "I'm on a Boat"...on classroom instruments. The funny guys were the latest guests for Fallon's recurring bit, which was great to see since the host and Andy Samberg only collaborated once on Saturday Night Live.

Rocking sailor suits that were made a little cooler with dark sunglasses, The Lonely Island, Fallon and The Roots crew got their jam on (unfortunately sans T-Pain and profanity) with xylophones, rubber duckies and mini tambourines.
