"Some friends and I were sitting in the living room and someone mentioned taking out the trash. We all quickly put our fingers on our noses (i.e. the nose game -- the rule being that the last person to touch his nose has to do whatever the task/dare at hand is). At that moment, another friend walks into the room. The following conversation ensues:

Me: You just lost the game.
Him: No. You did.
Me: What? No, I didn't.
Him: You definitely did.
Me: OH! No, I didn't! I was talking about the nose game.
Him: Dammit."
