Our YouTube hero for the final show is the unique Samwell, whose 'epic anthem' What What (In the Butt) has propelled the Chicago unknown to internet fame. His video, added to YouTube only a year ago, has had a phenomenal 8 million hits, and Samwell has found himself in high demand ever since. We think there's a bit of a hidden message in his song somewhere, but just can't work out what it is... See if you can.
