The rules as seen by rugby supporters:

• No knock-ons
• No offside
• No passing
• Every catch off the boot is a fair catch
• Goalpost crossbar to be taken down, snapped in half, and planted either side of uprights
• field must be as large as possible. Out of bounds only required because can’t make the ground any bigger and still fit in the stadium
• professionals must play the same as little kids and all swarm following the ball around the field
