Brian Williams is rapping again (with help from Kathie Lee Gifford)

There's just something about seeing Brian Williams say, "I like big butts and I cannot lie."

It's another Jimmy Fallon production: Williams is doing his Nightly News version of Sir Mix-A-Lot's famous Baby Got Back. The added treat this time: Kathie Lee Gifford is among the friends helping him out.

Past raps from Williams/Fallon include Gin and Juice and Rapper's Delight. We think this one's the best. How 'bout you?
