4. Shane McMahon's Lockbox
David Lynch movies make more sense than the entire Vince-Shane-Undertaker-WrestleMania 32 kerfluffle, where control of the company, and Undertaker's career (for some reason), hung in the balance. The only actual curious element was Shane blackmailing his dad.
Apparently, Shane possessed some lockbox that contained damning information about Vinnie Mac, and Vince desperately wanted to get his hands on it. We can only speculate as to its contents, because before long, WWE stopped bringing it up as a plot point.
