The Best Guest

The problem with this snarky sign is that most likely, people won't know who they are. In fact, I'm pretty sure that the guests who bring happiness by coming will think they are the ones who bring happiness by leaving, and they might leave, which would make you sad. Alternately, guests who you want to leave are obviously clueless (they won't leave no matter how many times you yawn, look at the clock, and change into your pajamas), and will think they bring happiness by coming, and will stay longer. Maybe even forever. Or they will come more often. Like everyday. This would be terrible.

Have I sold you on having this sign in your home or what?!
