LOGAN PAUL claimed Floyd Mayweather hasn't signed a fight contract yet because the boxing legend cannot spell in his own name in a cringeworthy video.
The YouTuber, 25, posted a clip from a gym punching a bag while calling out the undefeated five-weight former world champion.
And he questioned why the boxing legend, 43, had not put pen to paper on a deal for the pair to meet in the ring.
Paul said: "Hey Floyd, I know you've had the contract for a while now.
"At first I thought you didn't sign it because you didn't want one punch to ruin your legacy."
Paul wants to fight one of boxing's greatest of all time - claiming he would 'snap Mayweather in half' with one punch.
That is despite the American failing to even defeat fellow YouTuber KSI in either of their slugfests.
And things took a bizarre twist in the video when he embarrassingly started spelling out Mayweather's name which he had printed out and stuck on the wall.
Paul's weird rant continued: "But now I feel like maybe you didn't sign it because you don't know how to spell your name.
"Don't worry, champ, I've got you - check this out. I made you a cheat sheet."

Pointing to the letters sellotaped to the wall in his gloves, Paul added: "This is your name. Floyd Mayweather.
"It's pretty simple - it starts with an F."
Then the W in Mayweather fell off the wall, prompting him to add: "F***. Well, yeah, you ain't getting the W anyway.
"Then an L - your first L. O-Y-D. May. Eather.
"Sign the f***ing contract, Floyd."
Mayweather is due to return to the ring for the first time since New Year's Eve in 2018 next February.
But the 50-0 superstar, who beat Conor McGregor in his 50th pro bout, suggested he would take on Paul in an exhibition bout before the event in Tokyo - and would not go lightly on the online sensation.
The 43-year-old tweeted: "These YouTube girls better find some Barbie dolls to play with cause I’m not the one for the kid games.
"Three years ago a fighter from the UFC said my name and I had to put a muzzle on that b****.
