Jimmy Fallon's Ragtime Gals performed a barbershop quartet version of Sir Mix A Lot's "Baby Got Back" to loud cheers from his audience.
Starting with the PG introduction of "Oh my golly, Becky," Fallon kicked off the song while dressed in his multi-colored costumes with his fellow singers A.D. Miles, Tom Shillue and Chris Tartaro.
Fallon only broke into laughter a few times during the song, first when the singers got a bit off track during the lyric, "even white boys got to shout, baby got back."
