It was sometime around 2003 that, while watching SNL cast member Jimmy Fallon and guest host Justin Timberlake debut their absolutely brilliant The Barry Gibb Talk Show, we laughed so hard we nearly fell off the couch and broke our collective hip.

Fast forward to 2013 and the dynamic duo have created history again by making fun of famous musicians and their songs... again.

This time it’s The History of Rap, part 4 of which debuted just the other day on Late Night With Jimmy Fallon. In this exciting episode, Jimmy and Justin pay tribute to such greats as Going Back to Cali (LL Cool J), It’s Tricky (Run DMC) and Lose Yourself by the great, yet recently invisible Eminem.

Yes, you’ll want to see this. And yes, you’ll also want to see Part 1, Part 2 and Part 3. And yes, no matter how long it takes to watch them, it will still be infinitely less time than it takes to watch the never-ending ending of the third Lord of the Rings movie. That’s gotta be worth something, right?
