There are few things that make neutral rugby fans more excited than Nigel Owens telling a player to "Come yure!", knowing that the large athlete is about to get a dressing down from the superb Welsh ref.
Owens does it better than anyone else, and you can tell the players respect him for it, but after Sergio Parisse got a bit too yappy at the breakdown against Leicester in the European Champions Cup, he was told in no uncertain terms to cut it out.
When he did it again, he was given a flashback to his disobedient school days in vintage Nigel Owens style:
It doesn't matter if you're a newcomer or a veteran of the game like Parisse, if you cross the boss, you'll get told off. While Sergio shook his head in disagreement initially, he did see out the game as he took Nigel's advice.
And he was only put in charge of one Six Nations match...
