While interrogating Sharon Osbourne, Decker asks her if she bit a head off a bat, to which Sharon responds that it actually was her husband who did that. This is a reference to a real event, during which Sharon's husband Ozzy Osbourne bit a head off a bat during a live show. This event took place in Des Moines, Iowa, U.S. on January 20, 1982.

After the show he went to a local hospital to get rabies shots.
