BOXER Brandon Scott stole the press conference show by dressing up as SPIDER-MAN, calling himself a "scrawny nerd" and discussing the size of his manhood.
Scott will appear on the undercard of AJ's latest fight this Saturday.
Joshua faces replacement Robert Helenius, who has filled in for Dillian Whyte after a failed drug test.
And Scott said: "You know s***'s hit the fan when Spider-Man's been called to save the day.
"Look, I know what everyone here's thinking, I'm thinking the exact same thing... 'what is he doing here?'

"The only thing I can put it down to is obviously there was all that trouble with the positive tests and Ed [Hearn]'s gone, 'Right, who can I get on the show that's definitely clean?'
"He's looked at the list of his boxers, seen my name and gone, 'Right, if there's anyone that's not on something, it's that scrawny nerd.'
"But look, I could never turn an opportunity like this down. I mean Anthony Joshua is my biggest inspiration in boxing.
"I actually see a lot of myself in Anthony Joshua. Well, besides the muscles, the money, the penis size.
"He can't help that, I'm just genetically gifted."
