Everyone is talking about Stephen Colbert, but don't fool yourself: Jimmy Fallon is the king of late night tv.
Last night Jimmy flexed his chops by bringing out Justin Timberlake as a surprise special guest. If bringing out JT to chill wasn't enough, the dynamic duo teamed up to teach the masses about rap with a clever karoke performance.
Fallon is HILARIOUS during his skit with JT last night.
The duo let loose classics from LL Cool J to Bone Thugs... even an R Kelly remix thrown in for good measure.
