Osbourne was known for his outrageous behavior – allegedly biting the head off a dove during a 1981 record company meeting and allegedly doing the same to a bat during a 1982 show in Iowa.

One of Osbourne's final ventures included selling cans of Liquid Death with "trace DNA." A can sold on Ebay for more than $4,600.

Ozzy Osbourne is selling trace amounts of his DNA on empty Liquid Death iced tea cans he's drank from. Only 10 cans with the Prince of Darkness' saliva remnants were available for purchase at $450 each.

Travis Barker owns a Liquid Death can containing Ozzy Osbourne's DNA. The Blink-182 rocker was one of 10 people to purchase the cans sold for a cool $450 each.
