#2 Bret Hart and Goldberg
This entry on the list is the only one that didn't happen under the watchful eye of WWE, and might very well be the most shocking. Goldberg and Bret Hart, two men who basically hate each other, were once WCW's Tag Team Champions together.
Goldberg would infamously misplace a superkick on "The Hitman" which would begin Bret's slippery slope to retirement. Before that though, while Hart was WCW Champion, he and Goldberg set their differences aside in order to become Tag Team Champions.
While it wasn't the shortest on this list, their reign didn't last long. Just a week after they won the belts they lost them to the team of Scott Hall and Kevin Nash. No surprise there and another couple of WCW guys that Hart wasn't too fond of.
