It's just practical...
This man walks home from work. On the way home he stopped at the hardware store and bought a bucket and an anvil. Then he stopped by the livestock dealer and picked up a couple of chickens and a goose. However, he now had a problem: how to carry all of his purchases home. The owner said, "Why don't you put the anvil in the bucket, carry the bucket in one hand, put a chicken under each arm and carry the goose in your other hand?"
"Hey, thanks!" the man said, and out the door he went. But in the parking lot he was approached by a little old lady who told him she was lost. She asked, "Can you tell me how to get to 1603 Mockingbird Lane?"The man said, "Well, as a matter of fact, I live at 1616 Mockingbird Lane.Let's take my short cut and go down this alley.
We'll be there in no time."The little old lady looked him over cautiously, then said, "I am a lonely widow without a husband to defend me. How do I know that when we get in the alley you won't hold me up against the wall, pull up my skirt, and ravish me?" The man said, "Holy smokes lady! I am carrying a bucket, an anvil, two chickens, and a goose. How in the world could I possibly hold you up against the wall and do that?" The lady said, "Set the goose down, cover him with the bucket, put the anvil on top of the bucket, and I'll hold the chickens."
