Shawn Michaels and Marty Jannetty made up one of the most consistently great tag teams of the late 80s, and are actually somewhat famously known for NOT having won the WWF Tag Team Championships.
Except that technically, they did. In 1990 The Rockers actually defeated The Hart Foundation in a two out of three falls match to win their very first (and last) titles together in WWF.
During the match, the top rope actually broke free, and the company decided to run an angle where President Jack Tunney overturned the decision and gave the titles back to the Harts. In reality, the video production crew tried their hardest to make the footage work, but the technology wasn’t quite there in 1990 and it would have taken an enormous effort to cut together a version of the match suitable for airing on television.
