Another reason I should not be allowed to raise kids

So, while preparing to leave hotel on Sunday, Dave innocently said, "I'm going to get the "doo-ma-floppy." I knew he meant "thingamajiggy," or more specifically, "the luggage cart." The kids were very excited. A doomafloppy sounded so exciting! They wanted to go with daddy to get the doomafloppy. They rode it, hung upside down on it, and three days later, are still referring to it as a doomafloppy and asking why we all keep laughing.
