If anyone wasn't convinced that The Tonight Show with Jimmy Fallon wasn't different from the Tonight Show starring Jay Leno, Friday, February 21st's episode had to have changed their mind.

Friday's episode only had one guest, Justin Timberlake. Timberlake and Fallon are great friends and they form a great duo. They have had fantastic skits on Saturday Night Live, and their History of Rap songs on The Late Show with Jimmy Fallon have been epic.

The question was, would they repeat that at 11:30 and give us The History of Rap Part 5? Well, no sooner had Timberlake sat down that the two of them looked at each other, at the audience, at each other again, and reached for the microphones. The result.... History of Rap Part 5!
