When Kota Ibushi first spoke with WWE, he had no clue who the head man was.

At the June 23 WWE Cruiserweight Classic taping, Kota Ibushi will be taking part. The Japanese star is among 32 wrestlers taking part in this multi-week event, which is set to crown a winner in September.

Ibushi made his first WWE appearance at the NXT TakeOver: Dallas live special. Cameras panned to him in the first row of the audience. However, earlier that evening, Ibushi had quite the experience, according to Enuhito, a Japan wrestling reporter.

The former NJPW star apparently went backstage sometime during the show. When Ibushi first went back there, he gave a “high-five” to a “big man”. Out of all the people in the building, that “big man” turned out to be Vince McMahon, owner of WWE. Ibushi had no idea who he was, which made the staff “really upset”.

WWE then negotiated with him for a while, presumably for the Cruiserweight Classic. After the company kept making offers, Ibushi finally said yes.

Ibushi having no idea who McMahon, the owner of the biggest wrestling company in the world, makes for an awesome story. While some may have been upset that he didn’t know the Chairman, Ibushi will likely turn those frowns upside down at the Cruiserweight Classic taping.

So what would you do if you unknowingly gave a “high-five” to the owner of WWE?
