Newcastle boss Joe Kinnear recently made the headlines for his foul-mouthed outburst at a group of football hacks.
But it was a verbal onslaught from another JK - John Kingston - which pushed Harlequins to victory at Llanelli Scarlets on Saturday.
Quins found themselves 19-3 down at the break in their opening Heineken Cup clash of the season before head coach Kingston gave it the hair-dryer treatment.
And his side responded with a stunning second-half comeback to win 29-22 for their first success in the competition in almost seven years.
The main target of Kingston's rollocking, Chris Malone, even went on to become man-of-the-match.
Malone said: "I don't know whether you could call them words of wisdom, but they were definitely some strong words.
"I especially, and a lot of us, got an absolute rollocking from the coach at half-time, and we had to get things in order.
"They had come out and smashed us in the first half. We were allowing them to play in our faces, and if you sit back against the likes of Stephen Jones, David Lyons and Regan King, you are asking for trouble.
"We had to get back to playing our game, apply some pressure, and it told in the end."
Yet the damage might have been irreparable if Malone, Gonzalo Tiesi and Mike Brown hadn't made vital tackles before Quins finally got their house in order.
Malone said: "It could have been a lot more than a 16-point deficit at half-time. There were a couple of good tackles.
"Gonzalo put in a good one, as did Mike Brown, and if they scored either of those tries it was going to be hard for us to turn it around.
"But we were beaten by London Irish when we led them 20-3 the other week, and we said that if we applied some pressure, there was no reason why we couldn't do that too."
Malone's two early penalties cut the deficit in the opening minutes of the second period, and despite Stephen Jones adding a penalty, Danny Care's try just before the hour mark helped set up an unlikely turnaround.
And with Quins making use of strong bench to bring on Tani Fuga, Nick Easter, George Robson, Epi Taione and Andy Gomarsall to turn the screws, they romped home in some style.
Malone said: "Look at our bench. There was a lot of experience, and that's the great thing about having a good squad.
"It's a great start, but Ulster this weekend are going to be a challenge.
"They've had a big defeat against Stade Francais, and they'll come to our place wanting to win, so we can't afford to perform like we did in the first half against Scarlets.
"We let the Heineken Cup pass us by last year. It was one of those things we were just happy to be in.
"But we showed by almost being in the top four in the Guinness Premiership that there's ambition, and we want to take things ahead.
"This year we vowed not to get to the end of the group stage and think 'where did that go?'"
