Contagious

In school the lesson was about the word "contagious." The teacher asked the class if anyone could use the word contagious in a sentence.One girl raised her hand and said, "I had the chicken pox and I couldn't go outside and play because it was contagious."The teacher replied, "That was good. Can anyone else use contagious in a sentence?"One of the boys said, "I couldn't go over my friend's house because he had a cold and my mother said it was contagious."The teacher replied, "That's good. Anyone else?"Little Johnny said, "Last week when we had the snowstorm, my father took the snowblower and blew all the snow into my neighbor's driveway."The teacher was upset and said, "That was a horrible thing to do. And besides, it has nothing to do with the lesson."Johnny spoke up, "Yes it does. My father came in the house laughing, saying it will take the contagious to shovel herself out."
