Tyson Fury made an abrupt exit from Thursday's press conference to preview his rematch with Dereck Chisora, tossing the top table aside and storming out after promising to knock his opponent out.
Fury had done most of the talking in London on Monday at the initial media event for the 26 July heavyweight bout, hurling a series of insults at Chisora.
But on this occasion in Manchester the 25-year-old kept things far more brief.
When asked for his opening remarks, Fury said: "All this mumbo-jumbo, great fights and all that - basically, let me tell you straight how it is."
He then stood up, grabbed a microphone, and declared: "Listen, I'm Tyson Fury, I'm the best heavyweight on the planet, this idiot is getting knocked spark out and I'm sick to death of this."
He added: "This m********r is going to sleep" before slamming down the microphone, attempting to flip the table over, jumping down from the stage and heading out of the room.
An unimpressed-looking Chisora simply sat and applauded what he had seen in a sarcastic manner.
The 30-year-old had remained calm as Fury had taunted him on Monday and was again composed on Thursday.
Chisora said: "What can we say about that? Shall we give him a Golden Globe or not? He needs to get a bit of publicity - he needs people to talk about him. But we just laugh."
Chisora himself has a reputation as a hot-head, having slapped Vitali Klitschko across the face in the build-up to their 2012 world title bout in Germany and then brawled with David Haye at the post-fight press conference.
But he has subsequently taken part in anger management sessions, and emphasised on Thursday that he is more on top of his emotions these days.
"My emotions are more calmed down now," Chisora said.
"With him (Fury) swearing at me, two or three years ago we would have been rolling around on the floor right now.
"I'm not a punk - don't look at me and think that. I'm more of a gangster than anybody else.
"But, as you can see, right now I'm very calm. I'm a boxer, a professional athlete now."
In the first meeting between the pair in 2011 at Wembley, Fury claimed the British and Commonwealth titles with a unanimous points victory over Chisora, who admitted he had not been fit enough for the contest.
The latter goes into this encounter - which is a WBO title eliminator - as the European champion, while the vacant British title will also be up for grabs.
And Chisora, victorious in his last five fights following defeats to Klitschko and Haye, is looking ahead to the bout in confident mood.
"I don't have much to say because the person I want to say it to is not here," Chisora said.
"There is no need for me to badmouth him while he's not here - I'm not a backstabber. I like to tell the truth in front of people's faces.
"I have made my name already and we know Tyson hasn't been on the biggest stage in his career so far.
"He needs to understand I'm giving him another payday. I am the champion.
"The first fight was great - he trained hard, he came to take the titles and he did that. But this time, it will be different."
Asked if he had learned lessons from the first meeting, Chisora (20-4, 13 KOs) said: "That he hasn't got much power - he couldn't knock me out."
And when it was put to him that the unbeaten Fury (22-0, 16 KOs) has been talking about knocking him out in the fifth round,
Chisora said: "I'll do him in the first round!"
The WBO title is one of those currently held by Vitali's brother Wladimir Klitschko - also the WBA and IBF champion.
And although the winner of Fury v Chisora will get a shot at the WBO belt, the former's promoter Mick Hennessey is not convinced that will involve a clash with the Ukrainian.
Regarding the 37-year-old Wladimir Klitschko, Hennessy said: "We have reached out to him quite a few times now and said we would be reasonable and sit down and negotiate, but they have never come back.
"Wladimir doesn't want that fight because, in my opinion, he doesn't fancy the job.
"So Tyson is fighting for the mandatory spot, he'll get that and let's see if Wladimir defends against him once he comes through."
