 Once upon a time there lived three energy hogs. Now an energy hog is what you have when humans waste energy. One day the three energy hogs set out to find themselves a cottage. Let's look for leaky windows, said the first energy hog, for he knew that would waste energy. Let's look for leaky doors, said the second. Let's look for a swing set, said the third, for he had more blubber than brains. So they set off down the road. Presently they came upon a tiny cottage where dwelled a clever girl named Dreadilocks.
