If you want to see a real live argument where everyone disagrees, then just watch a football game. This is a photo I took from the television, hence the not so good quality. It was the UEFA League Final in 2008 when Manchester beat Chelsea 6:5. I cannot remember the exact details, but probably Manchester won by penalty as the score is otherwise not so high. It seems that everyone was disagreeing here.
Being a referee at such a game cannot be fun.
