A lady goes into a store to buy some cat food. The cashier says, “I’m very sorry, ma’am, but we need proof that you actually have a cat. Some people nowadays will buy cat food to eat.” The lady finds this odd, but goes home, brings her cat back and is able to buy the cat food.

The next day, the same lady goes to the store to buy some dog food. The cashier says, “I’m very sorry, ma’am, but we need proof that you actually have a dog. Some people nowadays will buy dog food to eat.” The lady feels slightly annoyed, but goes home, brings her dog back and is able to buy the dog food.

The next day, the same lady goes to the store to buy some baby food. The cashier says, “I’m very sorry, ma’am, but we need proof that you actually have a baby. Some people nowadays will buy baby food to eat.” By now the lady is feeling well and truly irritated, but goes home, brings her baby back and is able to buy the baby food.

The next day, the lady goes to the store and approaches the cashier, holding a small box with a hole in the front. “Please put your finger in here.” she says. The cashier gives her an odd look and says, “Absolutely not, you might be hiding a spider in there.” The lady replies, “Please don’t worry, I’m not.”

The cashier is still skeptical. “Are you hiding a rat?”

“No.”

“A snake?”

“No.”

“Well….All right.”

The cashier puts her finger in the box and touches something soft and squishy; she pulls her finger out, smells it and says, “This smells like poop!”

“Exactly,” the lady replies. “Now can I buy some toilet paper?”
