Tyson Fury warmed up for his world-title eliminator by threatening to knock out Dereck Chisora.
The 25-year-old then flipped over a table before storming out of a news conference to promote the heavyweight clash in Manchester on 26 July.
"Listen, I'm Tyson Fury, I'm the best heavyweight on the planet," he said. "This idiot is getting knocked spark out and I'm sick to death of this."
An unmoved Chisora, 30, replied: "Shall we give him a Golden Globe or not?"
The winner of the fight will go on to challenge IBF, WBA and WBO heavyweight champion Wladimir Klitschko.
Manchester fighter Fury hurled insults at his opponent during Thursday's press conference in his home city, just as he had at Monday's news conference in London.
But Londoner Chisora added: "He needs to get a bit of publicity - he needs people to talk about him. But we just laugh."
Fury beat Chisora on points the last time they met, in 2011.
Chisora's European heavyweight title will be at stake, as well as the vacant British title.
