2. Vince McMahon vs Hulk Hogan
These two have been swinging between boozin' buddies and mortal enemies for decades. They have argued over who created Hulkamania, who made WWE what it is today, and who has the biggest pythons. Both men deserve credit, and both men deserve a tonne of criticism - one thing neither of these men want to hear said about themselves. Their competition has become personal on several occasions. On one particular occasion, Hulk Hogan testified against McMahon in his lawsuit with the federal government over steroid abuse. That could have ruined McMahon. Hogan also jumped ship and went to help WCW climb above the WWE in the ratings, and almost put his old team out of business. I don't understand how you just forget about all that and welcome somebody back to work with you, even if over a decade of time has passed. I guess that's why I'm not a billionaire, or a millionaire. The two of them more often than not conveniently patch things up in order to make money together. Hogan described their current relationship as "fine" in an interview only a few months ago, sparking widespread rumours about his possible involvement in Wrestlemania 30. If I were Vince, I wouldn't even allow the guy in the building on principle, but if it's "best for business", Mr. McMahon will put his grievances aside. That's how you make money in wrestling.
