I heard the entire management team at corporate is trying to leave so they're playing rock, paper, scissors to see who gets to go next. Since no one there ever heard of rock, paper, scissors, Mark explained that when he counts to three, they should hold their hand out and keep their fist closed. He counted to three then placed his hand flat over theirs and said "I win." They had no idea what he was talking about. I find this works well with my DM as well when I want something.
