MY NAME IS STEVE-O AND THIS IS ...
Michael Bisping briefly came out of retirement Saturday night, choking Steve-O unconscious in a UFC Octagon ... while the Jackass star refused to tap!
It all went down at the UFC APEX Center on Saturday in Las Vegas. Steve-O was in the building to watch the UFC Fight Night card ... but got in on the action himself after all of the fights were settled.
The clip starts with 44-year-old Bisping standing behind Steve-O, and he has him in a rear naked choke.
