Maria has a history of wrestling in tons of different organizations including TNA, New Japan Pro Wrestling, and of course, WWE. I don't know anything specific about New Japan Pro Wrestling, but I have seen some Japanese wrestling videos. Those things get crazy. I've seen one where they had actual landmines in the ring. As odd as it is to say, I can understand chairs and even barbed wire ropes. Landmines seems a bit much.
Maria is currently in the WWE as the manager to her real life husband. That's a situation where reality blends with real life. Sure, she's actually his wife, but she's not actually signing contracts for him. In the WWE, manager just means "person who hits the other guy with a chair if the referee isn't looking." Not a bad gig when you think about it. I was a manager at Taco Bell and I never got to hit someone with a chair. Came close a few times though.
