The Old Live Oyster In Soup Gag
A cop is served oyster soup in a restaurant and discovers the oyster is alive, stealing his crackers. He fights with the oyster, stabbing it with a fork and tugging its fleshy interior. The oyster sprays soup in the man's face, causing him to remove his jacket and hat, revealing he's not really a cop. The man smashes the oyster with a club, causing soup to spray on a nearby patron; he inadvertently throws a vase in the owner's face and topples a waiter's tray full of food. The man and a friend are consequently chased from the restaurant, and in and out of sewer pipes piled by the road.
