Italy scored seven tries as they secured a bonus-point World Cup Pool B victory against Canada in Fukuoka.
But it was popular Welsh referee Nigel Owens who stole the show.
He told Canadian captain Tyler Ardron: "I won't give you a second warning. This is the official warning...speak to your side, the next time will be a card...and speak to yourself as well because you're the one giving away the penalties!"
Here are some other funny interactions the Welshman had during the game.
