I can remember seeing this happen in a game at Don Valley Stadium - Sheffield -v- Wigan, 1998 - it was the game the week after they'd beaten us in the Cup final. John Kear was sat quite high up in the stand, and we were sat behind him. We started giving the ref an ear bashing. Kear turned round, told us to pipe down because we didn't know the rules, and explained them to us. We were well and truly put in our place. Top man.
