National Geographic Taboo: Exorcism's (2012)

A love affair with balloons, a fetish for female bodybuilders, and a snuggle up to a shrunken head in bed… Taboo promises to be one of the strangest shows you'll see this year. Collectors reveal their obsessions, including London curiosity shop owner Viktor Wynd, whose store sells skeletons, alleged celebrity faeces and Russell Brand's hair to Jim's 'Noah's Ark' with 550 live animals, discover how some collectors' passions cross the line.

For many, collecting knick knacks or other objects is a hobby; for some, it's a bizarre obsession. Dug, a foot fetishist has over 300 pairs of shoes and 5+ million photographs of feet. While most collectors keep their collection in their home, Lonnie has allowed his collection to become his home. In Turkey, a potter's strange collection is hidden in an underground cave. What started as a childhood hobby for Lawrence has spun out of control forcing him to rely on his parents, and for one man in England, collecting bird ornaments is a full-time hobby.

In Indonesia, a young man kidnaps his bride, while in one village in India; pimps plot violence when a mass wedding threatens their trade.

Many cultures around the world believe evil can manifest in demonic spirits that enter a person's body. For some who believe, the only solution is an exorcism.

One minister in Jacksonville, Florida is trying to battle as many demons as she can. Aka Devils and Demons.

The grimy, nasty filth nobody wants to be around is an everyday sight for these dirty job cleaners. In Minneapolis, a team of heavy-duty housecleaners tackles a truly filthy, foreclosed house.
