A phrase first heard in the BB gun/coming of age movie The Christmas Story. This can be applied whenever a child wishes to butter up his father in order to gain a favor. Over reaching laughter and enthusiasm follows when a marginally funny line is uttered by the dad. It's usually a blatantly transparent attempt as the favor is requested only a short time after the "good one, dad."
Dad: "Look at that! I guess people in fancy cars don't have to obey stop signs!"

Son: (Fake laughter...) "Good one, dad! .......can I have twenty bucks"?
