Kevin Spacey showed up to help out Jimmy Fallon and his Ragtime Gals on Friday night's Tonight Show, and boy, oh boy, did they pick a doozy.
Jason Derulo's raunchy anthem "Talk Dirty" is not a song one would expect to hear as a peppy Barbershop number, but that of course made Spacey's and Fallon's performances all the more fun. Watch the whole act, below. --Sarah Eberspacher
