Billionaires are not an exception when it comes to weirdness. Although some billionaires' strange habits caused them to waste money on unnecessary and wasteful habits, there are also some whose weird habits have the good of mankind in their mind. Here is a list of those billionaires with their surprising fetishes.

Jeff Bezos

Jeff Bezos and Amazon are synonymous with each other. With an estimated worth of $20 billion, Bezos has undertaken several projects, some of which made sense while some don't. Aside from space and ocean explorations, the weirdest project he has started is the construction of a giant mechanical clock called Clock of the Long Now. It has cost Bezos $42 million in order to construct a clock designed to run for 10,000. What's weird, though, is that after construction, Bezos would bury it deep in the Sierra Diablo Mountain.

Peter Thiel

Peter Thiel was the co-founder of PayPal and an investor in Facebook. This billionaire is weird for his penchant for investing in extreme out-of-this world technology. One of his pet projects is to build floating cities in the sea because he thinks this is necessary for the survival of mankind. If you think that's weird, he also pours his money in hopes to find immortality and develop artificial intelligence.

Bill Gates

Bill Gates doesn't make it a secret that he loves reading. However, he loves it so much that he is willing to pay $30.8 million to become the owner of the Codex Leicester, a manuscript written by Leonardo da Vinci. However, it is still a mystery if he reads it every night or created a digital copy of it.

Sandy Lerner

Who would have thought that the Cisco co-founder and a woman at that would be so crazy about the ways of medieval England, especially jousting. Instead of waiting for the country fair to have her hands on medieval activities, Lerner has an 800-acre farm where she raises Shire horses made especially for jousting. She also owns period costumes, lances, and jousting paraphernalia.

Ingvar Kamprad

If you think Warren Buffet is frugal, wait till you meet Ingvar Kamprad, the owner of IKEA. Unlike all other billionaires who have yachts, flashy cars, and sprawling mansions, Kamprad drives a 20-year old Volvo and recycles tea bags. He even waits for post-Christmas sale to buy wrapping paper. His actual net worth is still under speculation because most of what he owns is set up as charities and other philanthropic works.
