Justin Timberlake helped Jimmy Fallon close out his debut week hosting The Tonight Show with the “History of Rap Part 5.”

Following a week of guest appearances that ranged from Bradley Cooper to Michelle Obama, was Timberlake – who had the honor of being the only guest on The Tonight Show on Friday night. Before Fallon and Timberlake began the fifth installment of their popular gag, the audience erupted in cheers.

Tone Loc’s “Wild Thing,” The Notorious B.I.G.’s “Big Poppa,” Run DMC and Aerosmith’s “Walk This Way,” the Fresh Prince of Bel-Air theme song, Salt ‘N’ Peppa’s “Whatta Man,” Kriss Kross’s “Jump,” “99 Problems,” by Jay Z and Drake’s “Started From the Bottom,” all made the cut for the latest “History of Rap” installment.

Timberlake and Fallon last teamed up for a “History of Rap” performance in March 2013 on Late Night’s Timberweek. However, their last music collaboration was in December, when they both appeared on Saturday Night Live’s Christmas episode.

Earlier on in his inaugural week at the helm of The Tonight Show, Fallon had a number of other musical moments, including Will Smith performing the "Evolution of Hip-Hop Dancing" and spliced together clips of Brian Williams to make the anchor appear to be rapping “Rapper’s Delight.”
