A Funny Bit on ‘The Tonight Show With Jimmy Fallon’ and a Surprise Guest [Video]

It's been a long-running Tonight Show With Jimmy Fallon bit, "Black Simon & Garfunkel," and gets lots of laughs. The other night, Black Simon & Garfunkel had a visitor.

Ah, yes, the real Art Garfunkel. Who are Black Simon & Garfunkel?  Two members of The Roots, Jimmy Fallon's band.
