Jimmy Fallon and will.i.am have united for a music video, and the result is definitely not “Ew!”

The pair dressed up as teenage girls as part of Fallon’s recurring “Tonight Show” segment, “Ew!”

Fallon, as usual, plays Sara, while will.i.am becomes mir.i.am. Together, the two create a musical manifesto of all things “Ew!” — including bread bowls, duck lips and “impleggies.”

One listen, and “Ew!” will probably be stuck in your head for all eternity, or at least for the rest of the day. But if you want more, the song is for sale as a digital download on iTunes.

Cost is $1.29, which is seriously not “Ew!” because the cash is going to the SeriousFun Children’s Network and the i.am.angel Foundation.
