I don't know if you have been watching Jimmy Fallon's first week on The Tonight Show, but he has brought his A-Game.

Last night he ran a clip (or clips) that has NBC's Brian Williams rapping the 1970's classic 'Rapper's Delight' by the Sugarhill Gang.

If you haven't seen it this it's well worth the minute and half out of your day.

Make sure you don't take a sip of coffee before hand or it could end up all over your desk from laughing so hard.
