#3 Pat Patterson - 20 Years and 2 Months

An incredible second entrant in a row for WWE Hall of Famer, Pat Patterson.
As mentioned, before Patterson ended his 19 year + drought of Championships, he had held the WWE Hardcore Championship in June 2000. Not only was it incredible to have won another Championship after that length of time when he won the 24/7 title, but his Hardcore title win was also the first time he held a Championship in WWE since becoming the inaugural WWE Intercontinental Champion.

Patterson became the first ever WWE Intercontinental Champion in September, 1979. He would hold the gold for 233 days before losing it to Ken Patera in April, 1980. Patterson only wrestled sporadically from then on, before retiring from full-time competition in 1984, and wouldn't hold a Championship again until his previously mentioned Hardcore title win in 2000.
