1. They are all wearing Welsh football shirts
2. The score is 1-1 (you can't score 1 point in rugby)
3. Welsh rugby supporters don't wear stupid yellow hats. We wear even more stupid things like daffodils and carry giant leeks

Now this is the important one -

1. I can't see anyone drunk or drinking pints of larger/cider!!
