Football and switching

One fantasy I have is to find a like minded partner. We both choose a football/rugby team. Has to be different. If one team wins and the other looses , then whoever has chosen the winner gets to choose whether they are the spanker or spankee.

If both teams win, then which ever team has won by the greatest margin gets to choose.

If both teams draw or win via scoring an equal number of goals, then there has to be a switching session.

If both team lose, then we both have to get punished by a third party.
