Who'd want to be a referee?
Many instant decisions will be required. These will at all times be taken in accordance with an encyclopaedic knowledge of the game, ignoring pre-match suggestions of pro-Rangers bias.

No thanks will be given and the only perks will be a cup of stewed tea and a badly-cooked pie.
