C.O.D. 98 years old

Jerry stands on a chair by a dinner table. He looks at the things on the table then looks at the audience. He says: "No breakfast again!" He picks up the newspaper and looks at it. He sees an advert which reads: "C.O.D. Order your food by post." Jerry has an idea. He writes on the newspaper, filling in the words for C.O.D. as "Cats or Dogs"
