In the epiosde "Tiger Tiger," the Brady's dog Tiger runs away and Bobby and his dad, Mike go to look for it. When they come home in the station wagon, Mike pulls in with the car and turns off the ignition. But watch closely as he is turning the key in the ignition. He is only pretending to do so and not doing a very good job of it! Does he even have a key to the car? Maybe they had a fake running car as well as their fake lawn. Lol
