Farmer Joe\'s pigs have decided to take a trip to outer space in Bus Driver Tom\'s bus! What naughty pigs! How will Farmer Joe and Bus Driver Tom find them? And how will they bring them back home again? Jonathan enjoys making people laugh. He also likes cars and anything that has wheels. One day, Jonathan was having a normal conversation with Alison about wheels and buses, and then he got an idea. He started with one sentence, and then thought of another, and then he put them all together to come up with this fun story.
