The Saturday Night match that I will never forget or at least, I will never forget the last five to ten minutes or so of it, was the one between Andre the Giant and Jake the Snake. Andre spent the entire match worried about that snake and couldn't wrestle Jake with any consistency. He would get the upper hand for a while and then he'd see that bag move.
Finally, towards the end, Jake threw that snake on him and it looked like Andre was going to have a heart attack. I've never laughed so hard while being afraid that I was going to see a man die onscreen. I could never tell if Andre was really afraid, but was taking one for the team or if he wasn't and just the best actor in the world.
