3. Pilko Pump Pants
http://www.youtube.com/watch?v=R3pvkjq-QLM While in Japan climbing a mountain Karl decided that his own personal Bucket List item would be to invent something to leave behind to the world after hes gone. The eventual invention turned out to be a pair of pants (trousers to us lot in Blighty) with a large zipped pocket made to be filled with a cushion on the backside. The idea is that if youre wearing them you can sit down comfortably anywhere you go - even up a mountain. And if you fancy a quick trip to the shops for bread and milk then simply remove the cushion and stick your shopping in the pocket instead. During the final episode of series 2 Karl surprises Ricky and Steve with a clip of his own as he sells the Pilko Pump Pants (all 15 of them) live on a UK shopping channel. He then takes it one step further by demonstrating the inventions many other uses with hilarious results.
