Little Johnny replied, "None, because the sound would scare the other two away." His teacher said, "No, but I like the way you think!"
Little Johnny replied, "Alright, now I have one for you. What goes in dry and hard and comes out soft and hard?" His teacher was shocked and said, "Little Johnny!" He replied, "It's gum! But I like the way you think!"
