The Tonight Show was straight flowin’ on a boat Monday courtesy of The Lonely Island.

The comedy trio, comprised of Brooklyn Nine-Nine star Andy Samberg and former SNL scribes Akiva Schaffer and Jorma Taccone, joined Jimmy Fallon and The Roots for a censored rendition of their 2009 hit “I’m On A Boat” — this time featuring a bevy of kazoos, but no T-Pain.

The Lonely Island are the third act to join Fallon for his popular Classroom Instruments segment in just six months; Grammy winners Adele and Sia (featuring Natalie Portman) were the last to partake in this late-night viral sensation.

Watch the performance above.
