You know the expression, "That takes the cake"? We use it to mean something that is the most extreme. For example, if someone is telling you about a really bad trip they had, you could respond by saying, "Wow, I've heard of bad vacations, but that takes the cake!" I think the expression originates from the olden days when people used to tell stories, and the best story would win a cake. I think we should revive this practice. Nothing cheers you up after a really bad vacation better than a cake.
