Best Of ‘Late Night’: Jimmy Fallon And Stephen Colbert Remind Us That Friday Is Part Of The Week

Stephen Colbert dropped by Jimmy Fallon’s Late Night to sing Rebecca Black’s “Friday.” Taking one of the worst song’s ever and making it hilarious means that we are in good hands with our new Tonight Show host.

UPDATE: It’s “Best of Late Night” week and this clip is from 2011, a time when Rebecca Black was at the height of her power.
