There was another huge guy called Man Mountain Montana. Same basic schtick...you absorb a bunch of blows in your massive gut, then do a mighty belly bounce that knocks the other guy down, then FALL on your opponent and squash him! ;-)

I believe that what is normally done, Alanabit, is that the opposing wrestlers get together backstage before the bout and discuss in detail how the upcoming match will go so they'll get all the moves choreographed right. They have to plan it out, because there's a good deal of risk of physical injury if you don't know the script well, and not a little risk of getting hurt even if you do. Those guys work hard for the money and they take quite a bit of damage as time goes by. The "bad guy" also has to put up with the public hating him...but some of them seem to relish it...and being a really hated "heavy" is a great ticket draw. ;-)

Long-running feuds are a staple of wrestling entertainment, so those are of course carefully planned as well by the wrestlers and their management. If a feud can draw other wrestlers and wrestling personalities in, so much the better. The public seems to have a boundless appetite for such vendettas which are really just a very sweaty form of soap opera.

But, yeah, those guys are real athletes, you betcha. It's a tough racket to be in.
