Saving the World

An overheard backseat conversation:

O: "When we get home, do you want to play Chef?"

E: "Let's play Plans to Make the World a Better Place. I have this great idea I don't want to forget."

O: "Tell me. Tell me now."

E: "No, let's wait til we get home. My idea is nothing bad, but I don't want mom to hear."

O: "Well, I have an idea. My idea is that we should take all the weapons in the world and destroy them. We can throw them all in the garbage."
