I Saw a Mushroom Cloud!

It's true! I saw a mushroom cloud today. Here in the United States! How could this be? Is this the end of the world?

Hardly. There's nothing to worry about folks. Let me tell you what happened. I was cutting grass today and there was this really large mushroom in the yard. I decided to mow right over it. When the blades of the mower hit the mushroom, the mushroom exploded into the air, causing a big black cloud - a mushroom cloud. Whew! I guess you all feel relieved now don't you? That's good.
