The following is a 100% true actual conversation I Overheard At Work:
Woman: I couldn't possibly care less about Kim and Kanye's wedding. It's all so stupid; that's all the news sites have been talking about all day. Who cares what designer dress Kim wore... (several hundred words omitted for brevity) ...and who all was there and how much the wedding cost and..."In fact she cares so little about the affair that she spoke about it for at least twenty straight minutes.
Minor kudos to her, I suppose, for saying "couldn't care less" instead of the bone-headedly wrong "could care less."
