Pinkfinger (1965)

An English voice talks to the Pink Panther, who is reading a book about secret agents, and suggests to the panther that he become an agent. Intrigued at this idea, the Pink Panther dons a trench coat, hat, and pipe and walks nonchalantly on city streets, looking for enemy spies. He comes upon a gang of foreign agents scheming to detonate a series of black-ball bombs, and when they realize he is following them, they shoot him with guns, lure him into a crocodile trap, and, under cover of darkness aboard a train, replace his cigarette with a bomb.
