We have a fun game for putting your napkin on your lap at mealtime.
We played this when I was a kid and have carried on the tradition.... When we're sitting down for dinner, everyone needs to put their napkins on their laps quickly, because as soon as the last butt is in a seat, we all yell "got my napkin on my lap!" The first one to say it is the winner! Sometimes we forget and only one person remembers - then it's a clear winner, sometimes we're all screaming it so loudly and together, it's just a big laugh-fest!
