Watch Alanis Morissette, Meghan Trainor Cluck 'Ironic' on 'Fallon

Jimmy Fallon and his Tonight Show crew have performed music in some of the most ridiculous ways possible: barbershop quartet versions of profane pop tunes, a Ladysmith
Black Mambazo-styled song about ice cream, an assortment of Neil Young impersonations. But the show achieved a new level of musical absurdity during Tuesday's episode, delivering an "all-clucking version" of Alanis Morissette's sensitive 1996 single "Ironic."

In the clip, Fallon is accompanied by Morissette and "All About That Bass" crooner Meghan Trainor to form "the Jagged Little Chicks," a play on Morissette's smash LP Jagged Little Pill. They hit the stage dressed in chicken costumes and literally cluck their way through the song, with Fallon fake-strumming an acoustic guitar and Trainor holding a bass.

The group delivers some impressive clucked harmonies – and midway through the performance, Morissette switches up her style for some cluck-scatting. The funniest moment references the dramatic pause in the original song, with Fallon playing up the intensity for an emotional staredown.rollingstone
