#6 Billy and Chuck

The gimmick in a nutshell: Two tag team partners developed an uncomfortably close relationship with one another.
Pro Wrestling has often been the home to gimmicks that threaten the masculinity of the audience. Gorgeous George was the originator of the idea, wearing fancy 'girlish' robes and possessed of golden curly locks. Others, such as Exotic Adrian Street and Adorable Adrian Adonis, took the gimmick one step further, as did the West Hollywood Blondes in WCW.
But Billy and Chuck were the ones to take the gimmick to its ultimate extreme, displaying affection for each other to the point where they were nearly married live on Monday Night Raw. However, that was the night the gimmick ended when the duo admitted they were just pretending to get attention and TV time.
Why the gimmick managed to work: WWE went all in on the gimmick, as did Billy Gunn and Chuck Palumbo. The right for same-sex marriage was a hot-button topic of the era, and the gimmick definitely played into that.
Rico, their hairstylist/manager was also added to the mix to give them the extra appeal.
