A little old lady went to the grocery store to buy cat food.  She picked up four cans and took them to the check out counter.  The girl at the cash register said, “I’m sorry, but we cannot sell you cat food without proof that you have a cat.  A lot of old people buy cat food to eat and the management wants proof that you are buying the cat food for your cat.”

The little old lady went home, picked up her cat and brought it back to the store.  Then they sold her the cat food.  The next day, she tried to buy two cans of dog food.  Again the cashier said, “I’m sorry, but we cannot sell you dog food without proof that you have a dog.  A lot of old people buy dog food to eat, and the management wants proof that you are buying the dog food for your dog.”

So she went home and brought in her dog.  She then was able to buy the dog food.  The next day she brought in a box with a hole in the lid.  “Would you please poke your finger in there?” the little old lady asked the store manager.  “No,” the manager said, “you might have a snake in there.”

The little old lady assured the manager that there was nothing in the box that would harm her. So the manager put her finger into the box and quickly pulled it out.  “That smells like shit,” she said to the little old lady.
