Oh, K!

Remember lunch hour when you were in school? You'd sit with your friends and crack jokes about classmates, teachers or current events and you thought you were funniest people in the whole world? You weren't, but that's all right. None of us were. It's not the point of the story.
For the most part, you'd all hold your own, topping each other's zingers with clever comebacks. But there was always one kid at the table who was a step or two slow and couldn't really contribute to the witty repartee... except every very rare once in a while, that kid would chime in with something absolutely perfect and just blow everybody way.
Welcome to the funny table, K-Mart.
