Jimmy Kimmel has instituted a clever and kicky new segment. It's Mashup Monday. All this month, he's putting two musical acts you'd never expect to see together on the same stage and letting them jam it out.

It got off to a rousing start last week when he combined ZZ Top and Weezer (to make Wee-Z Top) for a cooking version of "Sharp Dressed Man". Rivers, meet Rusty.

This week, he brought out the undisputed king of uptown funk, Morris (All is Vanity) Day and backed him with the sister group Haim for a sweet rendition of "Jungle Love". Oh-wee-oh-wee-oh, baby rubber bumpers!

Check out the slick arrangement and the soulful choreography. Morris Day and the Haim is hot!
