Jon Jones Disfigures Jackass Star Steve-O In Incredibly Stupid Stunt (VIDEO)

For some insane reason, Jackass star Steve-O has been hanging out with some MMA fighters, most notably, Jon Jones.

Jones took to Twitter and posted a video of him wrestling with the legendary comedian Steve-o.

That was fairly minor to the next stunt they pulled.

The 46-year-old Steve-O wanted to know what a ‘cauliflower ear’ felt like, so Jon Jones grabbed a hammer and did as he wished.

Steve-O has made a career of doing things like this, so we really shouldn’t be shocked at this point.
