A little old lady went to buy cat food.
The cashier said,
“Sorry, we can’t sell this without proof you have a cat. Some people have been buying it for themselves.”
So the lady went home, brought her cat, and was allowed to buy the food.
The next day she tried to buy dog food. Again, the cashier asked for proof.
So the lady went home, brought her dog, and was allowed to buy the food.
The following day, she came in carrying a small box with a hole in the lid.
She said,
“Go ahead, stick your finger inside.”
The cashier hesitated.
“What if there’s something dangerous in there?”
The lady smiled. “Trust me, it’s safe.”
The cashier put her finger in, pulled it out, and made a face.
“This smells awful!”
The old lady grinned and said,
“Great! Now I’d like two rolls of toilet paper, please.”
