Tyson Fury was in great spirits ahead of the weigh-in for his big rematch with Deontay Wilder, finding time to publicly mock the Bronze Bomber.
The fighters were relaxing ahead of the weigh in, with the pair able to see each other on their screens while it was also being shown to the Las Vegas crowd.
Fury began by waving at his competitor, who was seen leaning on fiancee Telli Swift while slouched on a sofa.
The Bronze Bomber replied by rubbing his cheek with his middle finger pointed in the direction of the Gypsy King.
Fury responded by blowing kisses towards the camera.

The next instalment of Fury's mockery was to lean over onto his brother, Shane Fury, and start playing with his hair, imitating Wilder and Swift.
The commentators described the pair as turning the pre-weigh-in into a "comedy show" as Wilder smacked his own bottom in response.
All parties saw the funny side in the end and it was great to see two fierce competitors able to put aside that rivalry for a minute to have some fun.
Fury weighed in at 273lbs ahead of the rematch, over 16lbs heavier than the first time the two met.
The Bronze Bomber also weighed in heavier than the first bout at 231lbs, a career-high for the American.
It has been over 14 months since they last faced each other, a bout that controversially ended in a draw despite many experts agreeing that Fury should have been awarded the victory on points.
Since then Wilder, 34, has dispatched Dominic Breazeale and Luis Ortiz, both by knockout.
The Gypsy King has also had two bouts in that time, defeating Tom Schwarz via TKO and Otto Wallin via unanimous decision.
For the UK audience, the ring walks are expected to happen at around 5am, which would be 9pm in Las Vegas.
With both fighters having never suffered defeat in their professional careers, something has to give.
