Jimmy Fallon and his crew's recent shift from "Late Night" to "The Tonight Show" has done NOTHING to stop them from putting out viral videos.

In their latest release, they no doubt spent HOURS AND HOURS going through video of "NBC Nightly News" anchor Brian Williams, meticulously pulling every lyric to the Sugar Hill Gang's classic "Rapper's Delight."

And it paid off.

It got more than 2.5 million views in less than two days, with no signs of slowing down.
