• Maye Musk wants people to stop egging Elon Musk on to fight Mark Zuckerberg.
  • "Don't encourage this match!" Maye Musk tweeted at podcaster and AI researcher Lex Fridman.
  • Fridman had suggested he'd be "all for" a Musk vs. Zuck jiu-jitsu match.

Maye Musk really doesn't want her son to fight Mark Zuckerberg in a cage match. 

"Don't encourage this match!" she tweeted at podcaster and AI researcher Lex Fridman on Thursday, adding two angry-face emojis to her post.

Fridman had suggested he'd be "all for" a Musk vs. Zuck jiu-jitsu match. Elon Musk gamely responded to Fridman, writing: "Let's go full MMA."

But Maye Musk has been spending the last day trying to prevent the throwdown from happening. 

"Actually, I canceled the fight. I haven't told them yet. But I will continue to say the fight is canceled, just in case," she tweeted.

She also tweeted at her son on Friday, asking him to knock it off after he proposed the fight take place at the UFC's Octagon in Vegas.

"Fight with words only. In armchairs. 4 feet apart. The funniest person wins," she wrote.

No date has been set for the fight, which Elon Musk proposed, Zuckerberg took the bait on, and may well end up being nothing but billionaire bluster on Twitter.

Even so, the betting odds for the fight are rolling in, and some Twitter users have taken it upon themselves to make posters for fight night. Musk seems pretty fired up, though he'll be up against a younger, fitter Zuckerberg who's had training in mixed martial arts for over a year.
