Friday (Jack Webb) and Smith (Ben Alexander) suspect that a gang of teenagers is responsible for a series of auto-accessory thefts. No sooner have the detectives begun their investigation than a young punk shows up with some stolen accessories in hand, hoping to collect a reward from one of the robbery victims. The kid's brashness, alas, proves to be his undoing. Curiously, though the title of this episode is "The Big Stubby", the character played by Howard Bert is identified in some sources as "Stuffy" Opal. ~ Hal Erickson, Rovi
