When Jimmy Fallon and Justin Timberlake get together, it can only mean one thing: time to set your DVR.

Whether it’s The Barry Gibb Talk Show on Saturday Night Live, “#Hashtags” and "Evolution of End Zone Dancing", we know that when these two team up it’s going to be magic.

But the real magic happens when they team up to perform the “History of Rap.”

The pair offered up Part 5 on the Tonight Show on Friday, and, indeed, it was awesome. But it made us want to take a look back at Parts 1-4.

It all began back in 2010 on Late Night, when they kicked it off with “Rapper’s Delight.”

Part 2 came the following year, with some Salt-N-Pepa, Nelly and the Dougie.

Then Part 3 included some Michael Jackson moves, big butts and Nicki Minaj.

But when it came to Part 4 last March, the pair debated whether to do it again. “Okay,” Timberlake finally said. “But this is the last time.” Prompting Fallon to respond, “Until the next time we do this.”

Apparently, there was a “next time” for the duo: The pair revived their act with Part 5, which closed out Fallon’s first week as the new host of The Tonight Show.

Tell us, which one is your favorite?
