And they gave us major BFF goals once more.
They just keep getting better.
JT filled a week of Late Night with new songs, greatest hits, fake arms, "The History of Rap" part four, and a barbershop version of "SexyBack."
After killing it in parts one and two, JT returns to Late Night for the "History of Rap, Part 3" with Jimmy Fallon.
Jimmy and Justin pull a Deathly Hallows and give us a "part two" to their masterpiece, "The History of Rap." It's just as awesome, and shows once again that The Roots are about as good as a band gets.
