(An old woman comes into the store, looking very distressed.)

Customer: “Have you seen my cat?”

Me: “No.”

Customer: “He looks like this.” *holds up a badly drawn picture* “I got my grandson to draw me it.”

Me: “I don’t think you’ll find your lost cat with that picture.”

Customer: “Why?”

Me: “It’s a dog.”

Customer: “Oh. But can you put this up in your shop window for me though? Just give him some pointy ears.”
