Kurt Angle was known for making a huge transition from amateur to pro wrestling and adapted quite well, eventually becoming one of the top talent in little to no time. Who's to say Kurt Angle wouldn't know how to apply a submission move he has seen been applied to many other wrestlers in the past?
That's the thing: you can't see how to apply the move because Foley's fingers are in the guy's mouth. You could watch 100 videos of the Mandible Claw and still have no idea how to do it. It takes 2 seconds to figure out how to do an ankle lock.
Mick Foley has a threshold for pain? Sure. Kurt Angle wrestled in the main-event of WrestleMania 19 with an injured neck, got surgery, returned in less than 3 months and won the WWE title. Kurt Angle's also been in two Iron-Man matches, won the only Armageddon Hell in a Cell which featured two of the masters of the cell in Triple H and Undertaker and wrestled Steve Austin to the point where Austin had no choice but to get disqualified at SummerSlam 2001. Kurt Angle can endure his fair share of pain.
Cactus Jack and Mankind are laughing at that.
I don't see a valid argument to vote Foley over Angle, this assumption that Angle won't know how to apply Foley's finisher just doesn't hold up. Kurt Angle's a quick learner and can adapt to situations faster than most wrestlers, as he has shown time and time again throughout his career.
The Mandible Claw isn't a wrestling hold like the other stuff Angle had to learn. Unless you have someone explicitly show you how to use the move, it takes a bunch of trial and error to figure it out, during which Foley can bite Angle's fingers until they are useless.
