"Lazy Sunday" Performed Live For The First Time (VIDEO)

It's been a few years since "Lazy Sunday," took YouTube (and the rap-comedy world) by storm. Yet, before last night it had never been performed. Appearing on Fallon, Chris Parnell and Andy Samburg changed all that. And for a bonus piece of awesome, they recruit The Roots for their backing band. (Also, look out for cameos by other Lonely Island members Jorma and Akiva.)
