A very old couple, who have been married forever, are sitting on their porch one night. Suddenly, the old woman reaches over and smacks her husband knocking him off the porch and into the nearby bushes. He crawls back up and asks, "What was that for?"

She crawls back up and says, "What was that for?" He replies, "For knowing there was more than one size"
