Johnny Knoxville just pulled off the unthinkable -- the "Jackass" star defeated WWE star Sami Zayn in their "anything goes" match at WrestleMania 38 ... with shocking help from his friend Wee Man.
The famous stunt performer just wrestled in his first match in WWE history -- against bitter rival Sami -- and not only did he hold his own, but he walked away with the W, too.
The former intercontinental champ, Zayn, dominated Johnny for most of the match -- but the tables turned when Knoxville got some much needed help from Chris Pontius aka "Party Boy" and fan-favorite Wee Man.
