Dude - how do you know so much about this topic?
I'm a life-long wrestling nerd. I was a mark all through grade school. As I got older, they pulled the curtain back, exposing more and more of the backstage aspect of the business. I was instantly hooked, and just learned everything I could. I found the stuff totally fascinating.
After college, I even began training with and working for a small independent wrestling outfit...for about ten-minutes. By that time, the business had changed dramatically. There were far fewer chances to make it, and I got out of it soon after.
It was fun meeting some old-timers and even some of the up and coming guys. It's surprising how many work the Indy circuit. At one time or another, our promotion brought in King Kong Bundy, The Missing Link, Sunny and Chris (Skip), Balls Mahoney, Shane Douglas, Sandman, CM Punk, Honky Tonk Man, Mick Foley, Southern Comfort, AJ Styles, The Executioner, Jerry Lawler, and more that I can't recall right now.
Some of the guys, like Bundy, do it for fun; meeting old fans and entertaining new ones. But, it was sad to see the ones who wrestled because they had to - they need the money, and this is all they can, or are willing to do. We were lucky to bring in guys like Foley when the WWF was still hot. Some of Vince's guys had grandfatered clauses in their contracts that allowed them to accept third-party bookings. Many times, it was the guys who signed on board during the Shawn Michales/Bret Hart era when business was very bad for Vince.
