Smith won titles within the WWE in three decades, from the 1980s to the 2000s. He headlined multiple pay-per-view events for the WWF and WCW, which included matches for the WWF and WCW world heavyweight championships. Smith also defeated his real-life brother-in-law Bret Hart for the WWF Intercontinental Championship in the main event of SummerSlam 1992 at London's Wembley Stadium, in front of an alleged 80,355 fans. Hart considers this to be his best match.
