Just a week in and Jimmy Fallon is settling in quite well as the new host of 'The Tonight Show,' and he's back with another Brian Williams hip-hop cover. This time to 'Rapper's Delight.'

The last video of Brian was him rapping Snoop Dogg's classic 'Nuthin' But a G Thang.' They edit footage of Brian from NBC Nightly News to make it sound as if he's actually rapping. I'm sure the editing is tedious and takes a while, but the finished product is always hilarious!
