Rule 1: Don't trip over your own feet during the opening ceremonies. It's not just about you, it's about the team.
Rule 2: If you're going to do a backflip, make sure you can actually do it. We have insurance.
Rule 3: No using the ball as a frisbee. That's not a thing. Don't @ us.
Rule 4: You must, MUST, wear the proper uniform for the event. No exceptions, no substitutions. We have an entire committee for that.
