When you hear "Everybody clap your hands!" *clap* *clap* *clap*" from the stadium PA system, you best get to clapping. When "YMCA" comes on, we want to see you dance as though you're dressed like a stereotypical American Indian. And when the wave comes your way, keep that thing moving. If you're just sitting on your hands when the water rushes over you, you'll look like a certified hater.
