Once upon a time there was a purple cow. I never saw a purple cow until I went to a zoo. I asked the zookeeper if I could take it home with me. He said, "Yes." I took it home with me. I had to milk it everyday. It always made cow's noises. It was very noisy. One day my cow went to town. This boy was painting a building. The cow ran into the ladder. It got painted purple. That's why we have Purple Cow Day.
