That sounds good to me.
A Disco ball drops to the center circle and the crowd are encouraged to support their remaining player by dancing like there's no tomorrow.
The Ref and Assistants each hold up scorecards at the end of the dance.
Hmmm.. I'm not sure about this one as it could be perceived as too boring for the American visitors (too high a chance of a very low scoring game or draw).
I propose that at each blow of the whistle, every player (including goalkeepers) must sprint to a corner flag.
Last man to touch one sits...
