Undisputed WWE Championship champion Mr. McMahon since

On September 16, 1999, Mr. McMahon was not only the owner of WWE, he was also the champion.

In an unscheduled match that saw Shane McMahon officiate, Triple H defended his newly won WWE Championship against the boss. During the match, “Stone Cold” Steve Austin delivered a stunner to the titleholder, allowing McMahon to get the shocking win.

McMahon was not WWE Champion for long, however, as he vacated the title on September 20, 1999.
