#4. Bret Hart and Goldberg
Goldberg is widely considered as the guy who sent Bret Hart into early retirement by kicking him directly in the head and causing a serious concussion. As a result, the two men do not like each other to this day.
But what most people forget amid their differences is that the two men were tag teams before any of this took place. While Hart was still the WCW Heavyweight Champion, the two men set their differences aside for a night and ended up winning tag team gold. They did not enjoy the longest reign though as just a week later, Hall and Nash, beat them for the titles.
