Season 9 (2007)

Pilkington left school with only one GCSE and a deadpan voice. The exam he passed was an E in history. That doesn't sound out of the ordinary, but when you look at the fact that Pilkington thought he had two GCSEs (one in English and one in Art), it turns out that he doesn't even recall taking the exam that he passed. Herein lies the brilliance of Karl Pilkington. He then went on to talk to some very clever people indeed.
