That was the moment Fergie KNEW he had won the battle ... and the Premiership title.
And on Saturday he must have wet his pants again as former Toon boss Kenny Dalglish cracked up on live TV.
Dalglish has apologised for his conduct during his post-match interview with Sky Sports on Saturday as he faced questions about Luis Suarez's refusal to shake hands with Manchester United defender Patrice Evra.
Minutes earlier Ferguson laid into Dalglish, Liverpool FC and everything Scouse, and Dalglish buckled under the pressure.
Like Keegan, Dalglish lost the plot. The 60-year-old Scot says he was not aware at the time that the Uruguayan had not shaken hands with the Frenchman and said on Sunday that he had been assured by Suarez that a handshake would take place.
Suarez has also apologised for his conduct, while the club's managing director Ian Ayre said the South American had misled his employers by indicating he was going to shake Evra's hand.
Dalglish said in a statement released on the official Liverpool website on Sunday afternoon: "Ian Ayre has made the club's position absolutely clear and it is right that Luis Suarez has now apologised for what happened at Old Trafford.
"To be honest, I was shocked to hear that the player had not shaken hands having been told earlier in the week that he would do.
"But as Ian said earlier, all of us have a responsibility to represent this Club in a fit and proper manner and that applies equally to me as Liverpool manager.
"When I went on TV after yesterday's game I hadn't seen what had happened, but I did not conduct myself in a way befitting of a Liverpool manager during that interview and I'd like to apologise for that."
Reds managing director Ayre earlier told the Liverpool website: "We are extremely disappointed Luis Suarez did not shake hands with Patrice Evra before yesterday's game. The player had told us beforehand that he would, but then chose not to do so.
"He was wrong to mislead us and wrong not to offer his hand to Patrice Evra. He has not only let himself down, but also Kenny Dalglish, his team-mates and the club.
"It has been made absolutely clear to Luis Suarez that his behaviour was not acceptable.
"Luis Suarez has now apologised for his actions which was the right thing to do. However, all of us have a duty to behave in a responsible manner and we hope that he now understands what is expected of anyone representing Liverpool Football Club."
Suarez issued his own apology.
"I have spoken with the manager (Kenny Dalglish) since the game at Old Trafford and I realise I got things wrong," he said in a statement on the Liverpool official website.
"I've not only let him down, but also the club and what it stands for and I'm sorry. I made a mistake and I regret what happened.
"I should have shaken Patrice Evra's hand before the game and I want to apologise for my actions.
"I would like to put this whole issue behind me and concentrate on playing football."
Suarez scored in a 2-1 defeat for Liverpool, with Evra appearing to taunt the South American by celebrating right next to him at the end of the match.
United boss Sir Alex Ferguson described Suarez as "a disgrace" and suggested he should never play for Liverpool again while Professional Footballers' Association chief executive Gordon Taylor branded Suarez's conduct as "disrespectful, inappropriate and embarrassing".
Taylor added: "If anything, Patrice Evra was the victim and he was prepared to put his hand out.
"These players are expected to be role models but if we have a situation where nobody accepts the findings of hearings and just carries on regardless, all you get is anarchy.
"Now the Football Association have to step in because the whole situation has gone too far.
"Suarez had a chance to put everything to bed yesterday, in front of a worldwide audience. The fact that he chose not to is, quite frankly, depressing."
Alan Hansen: "Liverpool FC made a statement that there would be a handshake.
"Luis Suarez was party to the statement. He knew about it and obviously agreed with it. To snub Patrice Evra was, in my view, totally unacceptable.
"The football club and the manager have given him total and unequivocal support through thick and thin.
"He has let Kenny Dalglish down, the club down and himself down."
