Only two episodes in the can, and already Jimmy Fallon has made more of his 'Tonight Show' gig than Jay Leno managed to squeeze out over the past couple decades. On his first night as host of the show, he got U2 to perform on a roof. Last night, he enlisted a trio of singers for a barbershop quartet cover of R. Kelly's 'Ignition (Remix).'

With the Ragtime Gals by his side, Fallon stuck some a cappella spice into Kelly's bump-and-grind classic. Even when they get to the part about getting drunk on Coke and rum and doing a little "bounce, bounce, bounce," Fallon and his crew bring an innocence and sweetness to the song. Makes you almost forget that song is pretty much a call for sex.

This isn't the first time that the Ragtime Gals have turned a song like this upside down. At his previous gig on 'Late Night With Jimmy Fallon,' the host and his group have tackled Color Me Badd's 'I Wanna Sex You Up,' Shaggy's 'It Wasn't Me' and Justin Timberlake's 'SexyBack,' which featured JT himself in the bright stripe suit and boater hat.

Now we're just waiting for Fallon to bring 'Slow Jam the News' to his new time slot.
