DILLIAN WHYTE left rival Tyson Fury stoney-faced after his "that's what she said" joke fell flat at their Wembley face-off.
The Gypsy King was unmoved for a while after the cheeky attempt at humour from his upcoming opponent.
But then the WBC heavyweight king did permit a wry smile.
A journalist started his question: "You've been trying so very hard for so very long to climb to the very top of the mountain…"
But Whyte jumped in with "That's what she said" before cracking into laughter.
Amid sighs and some laughter in the room, he quickly apologised for the crude gag.

Whyte added "Sorry, I joke," and then carried on laughing as he tried to compose himself.
Fury and Whyte finally went face to face for the first time ahead of their world title showdown on Saturday night at Wembley.
It was all very mild-mannered and respectful between the two fighters, with the champ even left red-faced after an accidental gaffe.
Describing the closeness of their relationship, Fury said: "We were good friends together, we went out for a drink, we ate together, we slept together."
