The Little Rascals / Our Gang
Don't know about y'all, but I grew up watching The Little Rascals and always enjoyed them.
There's one episode where the gang is shown with their own kid volunteer fire department. Complete with a dog powered fire engine and others pulled by goats and mules. The engine that has the dog inside it, also has a cat in a cage and the dog is tied up. A rope is pulled which drops a piece of wood that allows the dog to see the cat. When the dog sees the cat he then tries to chase it, but is standing on a looped belt, kind of like a treadmill. The dog makes the belt turn which then turns the wheels on the kid size fire engine.
Sure brings back memories.
