Melissa McCarthy clearly won Monday night's Lip Sync Battle with Jimmy Fallon on The Tonight Show, with a performance that's being called "epic," "gritty," and "the messiest, most entertaining lip sync ever." But Fallon did give it his best shot, expertly miming bad rollerskating during his lip sync of Melanie's "Brand New Key" and then later writhing around on the ground with a pillow during his lip sync of Zayn Malik's "Pillowtalk." But McCarthy had him beat with her performances of DMX's "X Gon' Give It to Ya" and, brilliantly, "Colors of the Wind" from 1995's Pocahontas, which must be seen to be believed.
