Top 10 memorable 'Late Night' Jimmy Fallon moments
1. 'History of rap,' parts 1-4
When Justin Timberlake and Jimmy Fallon put their minds together, there is nothing they can't do. The pair recently joined forces for a week of "Late Night" shows, and performed a fourth "History of Rap" compilation. We don't know if the future will have a fifth mash-up in store, but we sure do hope so, because these things are pure TV gold. The second of the four happens to be our favorite (to the left) and features verses from "Push It," "Ice Ice Baby," and "It Takes Two." Try not to boogie in your chair while you watch this one, we dare you.
