The World's Most Dangerous Man became the World's Most Dangerous Official for WrestleMania 13's era-defining, industry-changing bout between Bret Hart and Steve Austin, and he passed the airport ref test with appropriately flying colours, just about managing to squeeze his mammoth biceps into a cut-off striped jersey.
The MMA supremo was the absolute perfect choice to add legitimacy to Hart and Austin's submissions match, with the bad-ass background to boot - even if references to him as a 'real' fighter did threaten to undermine the work to some extent. Two months after fairly calling Bret bloodily rendering Austin stone cold, Shamrock, liking what he saw (a big fat cheque), returned from the Octagon to the squared-circle full-time.
