I'm surprised Katie Vick hasn't shown up here. Really surprised.
No one recalls how the Sting/Kurt Angle started? Karen messed and screwed Angle and Sting out of the Tag Team titles for giggles and then made Sting look like he was abusing her. Again, for the lulz. That led to the main event of Bound For Glory 2007.
Samoa Joe's feud with The Pope started because he just decided to send Green Hornet's sidekick to videotape Pope on his spare time.
Sheamus and John Morrison's feud started... Well, because it did. There was no real reason for them being scheduled to face each other every week until TLC.
