Jimmy Fallon, will.i.am Jimmy Fallon, will.i.am

Jimmy Fallon combined two of his favorite things — his "Ew!" sketch and music — for the first time on The Tonight Show.

The host enlisted the help of dated rapper-producer will.i.am for the ridiculous music video, which featured the pair dressed as their teenage girl alter egos, Sara and mir.i.am. The duo then rapped about all the things that make them say "Ew!" like butt implants, cat dresses and duck lips.

TV wigs: Yay or nay?

Watch the full video below. Does it make you saw "ew"?
