A young couple go to the Monkey Sanctuary with a friend. The friend mocks the little Monkey, who is playfully swinging from a used car tyre strung up on a tree. The friend teases and tempts the monkey with a banana, but finally eats it himself. He even has the cheek to throw the banana peel at the monkey. The Monkey throws it back at him and signals the rest of the troop of monkeys to attack.

The friends rush back to their cars. The boyfriend and girlfriend get away. They use Caltex with Techron. It cleans your engine, thus allowing greater reliability in starting the engine. The friend is stuck behind. By the time the friend starts his engine, the monkeys have taken his tyres. If the monkeys couldn't get the food, at least they figured they'd take something to play with.
