A couple of years ago, my (now) wife ordered her mother a battery case for Christmas because she had seen the same one at our apartment and mentioned wanting one. Since it was ordered using the gift wrapping options, we didn't open it when it arrived, and she gave it to her mother to unwrap. Her mother was quite confused when she unwrapped her gift and found a sushi-making kit. It's become a recurring joke in our family now that we need to check any gifts ordered from Amazon in advance to avoid accidentally giving someone a sushi kit.
