Over 26 years, Graham Barker of Perth, Australia, collected 22.1 grams of belly button lint. After saving it in three jars, he recently sold his collection to a museum:

"The raw material is worthless but as a unique world record collection and a piece of cultural heritage, of debatable merit, it has some curiosity value," he said.

While most people have a positive reaction to his collection there is "a small minority – usually women" who find it unappealing.

Mr Barker said he had come across a handful of other navel fluff collectors, but none had taken their hobby to such lengths. He explained: "One guy might have persisted, but he got married and his wife ordered him to stop."
