Karl Pilkington's Sleeping Bag

Origins
Karl Pilkington is known for his TV series An Idiot Abroad and its subsequent sequels, where comedian Ricky Gervais sends him on trips to experience various countries and cultures around the world. The events of the trips are usually to the dismay of Pilkington, who is usually shocked, bored or annoyed by the various customs he has to experience.

Effects
Born from "experiences" abroad, sleeping in the sleeping bag drains the body of all curiosity, leaving the user apathetic and uninterested in any new experiences.
