We have these ceramic cups that we have silverware in. They're each labeled "spoons" "knives" "forks". We store them face down so you grab a handle when removing it.
Every so often when unloading the dishwasher I'll slip a spoon into the fork cup. Or a fork into the spoon cup.
I love the frustration sigh when someone (wife included) snags a fork when trying to sit down with a bowl of cereal or ice cream.
They usually don't notice until they're already at the table.
