Jimmy Fallon and Justin Timberlake brought back their awesome "History of Rap" segment for a sixth time.
On Wednesday, the duo hit the "Tonight Show" stage and pummeled though familiar tracks by Beastie Boys, LL Cool J, Salt-N-Pepa, MC Hammer and Public Enemy, among many others. Hammer Dance included.
Backed by house band The Roots, they showed us once again they know their history of hip-hop. And the two were working pretty hard, appearing out of breath at times during the 6-minute-plus bit.
"La di da di, we like to party...We don't cause trouble, we don't bother nobody..."
