Spike’s Jimmy Fallon–derived Lip Sync Battle may be its own hit show with its own charismatic host (and a live version apparently in the works), but Fallon still knows how to put together a great matchup for his own program. Friday night the progenitor of the popular faux-singing showdown went head-to-head with Girls creator Lena Dunham. Fallon performed a lively rendition of Charlene’s 1982 single “I’ve Never Been to Me†and then rapped Run-DMC’s “Run’s House,†while Dunham, clad in sports gear so she had “room to flex,†(silently) belted out Queen’s classic ode to butts “Fat Bottomed Girls,†allegedly Tina Belcher’s favorite song.
