Veteran promoter Frank Warren tried to keep them apart while muttering "save it for December 1", the date of Deontay Wilder and Tyson Fury's fight at Los Angeles' Staples Center.
And yet seeing the 6ft 9in Fury confront the 6ft 7in Wilder was to be reminded of the raw appeal of many a heavyweight contest -- two colossal men each with the ability to inflict huge damage upon one another.
It was in sharp contrast to the mutual respect shown by Britain's reigning world heavyweight champion Anthony Joshua and Alexander Povetkin ahead of their recent bout at Wembley which ended with the Russian suffering a brutal seventh-round stoppage defeat.
Fury is the former WBA, IBF, WBO, IBO champion -- belts now held by Joshua.
The 30-year-old Fury remains undefeated in 27 fights and still regards himself as the "lineal champion" because he never lost his titles in the ring but rather, for a variety of reasons, during a two-and-a-half-year absence following his shock win over former champion Wladimir Klitschko in November 2015.
Fury, who struggled with mental health issues, returned with a farcical stoppage of Sefer Seferi in Manchester in June before beating Francesco Pianeta in August.
Wilder has 39 knockouts in 40 fights and, amid all the jibes, Fury said: "I think it's going to be quite hard because he's a unique fighter. There's not going to be too many people like Deontay Wilder about.
"But then again he's got the same problem with me," he added before the old routine resurfaced. "I see a man, a skinny little man with two spaghetti arms and two spaghetti legs and when I bang him on the chin he's going to do a little spaghetti dance."
But an unimpressed Wilder said: "He thinks that by talking like he did with Klitschko, and getting inside his head, it's going to be the same thing, but I'm a different person. You can't do that with me."
