The best one I can remember is the blowoff match to the Jericho/Goldberg mini-feud in WCW. Jericho had been calling out Goldberg for months, calling him "Greenberg" and developing his own 5-0 streak against Goldberg, using count-outs and impersonators to pad his list, kind of a knock on WCW padding Goldberg's epic winning streak. He even went as far as hiring his own security crew, including his head of security Ralphus, to lead him to the ring, leading into an awesome This Is Spinal Tap parody where Jericho gets lost on his way to the ring.
Jericho was set to do the job to Goldberg on PPV to blowoff the feud, but Bischoff had no faith in Jericho, called a meeting with both men to tell them it wasn't happening, and instead blew the feud off with a simple spear on the ramp.
This in turn created the heat between Jericho and Goldberg that ended with Jericho front face locking Goldberg in a WWE locker room and making big Jew Bill look like a bitch.
Everyone should know by now...you don't mess with Jericho!
