In the pilot episode, a suspect breaks loose and starts wreaking havoc in the station. Tough guy undercover cop Mick Belker jumps on the guy and wrestles him to the ground, all the while growling and barking at the man. Captain Furillo runs in and yells, "No biting! No biting!" As Belker pulls the guy, now back in handcuffs, to his feet, he looks at Furillo, shakes his head, and mutters to himself, "You bite off one ear...!"
