#3. Demetrious Johnson agrees to fight YouTuber Bradley Martyn

Popular fitness YouTuber Bradley Martyn recently made headlines for calling out multiple UFC stars and claiming he could defeat them in a street fight.

At first, he jokingly targeted Nate Diaz and managed to anger the MMA community with his nonchalance. Next, he refused to believe he would be beaten by Demetrious Johnson, who is unequivocally believed to be among the greatest ever to do it.

Thanks to UFC alum Brendan Schaub, he may get to test it out in real life.

After making the initial claim to Schaub, who was a guest on his Raw Talk podcast, Martyn could get the chance to measure his fighting prowess against 'Mighty Mouse'.

Schaub told the YouTuber on the Calabasas Fight Companion podcast that Johnson had agreed to fight him:

"I spoke to Might Mouse yesterday. I tell you, all fighters hit me up about you, I'm like Bradley's my boy, good dude...So I told Mighty Mouse, like,'[Martyn is a] Good dude, dude'. He's like, 'Yeah no doubt, just tell him I'm down.'"

Martyn responded that he was eagerly waiting for the clash to happen.

Watch his comments below:

This is a long-running theory that experts have refuted before, stating that the Cold War-era video of nuclear testing was done with special equipment built to withstand the blasts.
