Sir Alex Ferguson's hairdryer treatment is the stuff of legends that many of the best players he ever worked with would have received at least once during their spell under the Scot.
The infamous incident involving a flying boot and David Beckham in the Manchester United dressing room has been told many a time but another one of his former proteges has revealed another brilliant Fergie story.
Gordon Strachan, now manager of Scotland, played for Ferguson at both Aberdeen and Man United and has recalled how his manager reacted after the ex-midfielder was less than complimentary about his tactics during one particular European game.
During 'An Evening with Gordon Strachan' at Elland Road on Friday, Strachan described a time when the 'lunatic' Ferguson tried to push a Russian samovar (a heated metal container) over him - only for it to massively backfire.
"I regularly got the hairdryer treatment. You had to see it to believe it but I wouldn't have missed it for the world," Strachan said, as per the Daily Mail.
"We were in Romania (with Aberdeen) once, he changed the system. We were 3-0 up from the first leg and he was going to make it secure by playing 4-3-3. We were 2-0 down after 20 minutes so it wasn't working well and he kept blaming me for the whole thing.
"So after a wee while I just went: 'Your tactics are s***.' The whole bench went: 'Oh no.'"
Even then, Fergie had a presence that meant it would require either a very brave or stupid man to stand up to him in front of everyone else.
But what happened next actually left Strachan in stitches.
He continued: "At half-time, I stalled and wandered about the pitch hoping he'd forget it because there was nothing worse than getting it from him.
"But you know you are in trouble when you sit down and the two guys either side of you disappear in different directions.
"He used to wear black shoes, always shiny, and these shoes would come in and shuffle about, looking for someone. Then these shoes stopped and pointed at me: 'Oh no, here goes.'
"There was a Russian samovar with the hot water. He tried to push it on top of me but it was full of water and it just fell on his shoes. I started laughing, he tried to scoop the cups on to me which hit Willie Miller and Alec McLeish on the head, so I started laughing again."
So of course when Aberdeen were awarded a penalty in the second half who stepped up to take it?
Prompt another brilliant Fergie moment.
"Unfortunately I was on penalties. He was spitting on the touchline 'F****** Strachan!' I took the penalty against the biggest goalkeeper in the world and scored. I gave it the big 'un (to Fergie): 'Take that you b******'.
"He tried to get on the pitch to get me. The boys jumped on top of me before he could.
"So I've had it a few times but wouldn't have missed it for the world. It was fantastic. He's some man. A lunatic but one of the best managers you'll ever meet."
It's hard to imagine many of the prima-donnas of today's game being willing to take such treatment.
Who knows how Ferguson would react if he had overseen some of the Man United performances of the last few years?
We imagine it would be even worse than what Strachan had to deal with!
