Legend has it that on Jan. 20, 1982, Ozzy Osbourne bit the head off of a bat during a show at Veterans Memorial Auditorium in Des Moines, Iowa. On the 37th anniversary of the incident the Prince of Darkness is celebrating with a plush toy to commemorate one of his most infamous antics. In a tweet announcing the toy Osbourne wrote, “Today marks the 37th Anniversary since I bit a head off a f*cking bat! Celebrate with this commemorative plush with detachable head.” The bat was on sale through Osbourne’s online store for $40, but fans have already grabbed the limited edition merchandise.
