Alan turns his face upside down
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Alan looked confused throughout the task. He put two goggly eyes on his chin, a red piece of paper on his face and wore a fake beard, sticking his tongue out. At one point, one of the eyes fell off, so he drew an eyepatch on instead. He received 5 points.
