(I'm Dragonfighter reborn, by the way

)
I can't say I've heard of a "pool match," but it wouldnt surprise me in the least considering it's an FMW bout. ECW is pretty hardcore, but I can't think of any federation more insane than the Frontier Martial Arts Wrestling organization. I've seen Eiji Ezaki shootingstar press out of the ring, get his face sliced up with a fork, get stripped naked and beaten to a bloody mess, set on fire, have limbs broken, get hit by a motorcycle, cover Taka Michinoku in a pile of chairs and Asai moonsault onto him, get wrapped with barbedwire, hit with boards, chairs, nails, baseball bats, crutches, get put through stacks of tables, getting nuked by pyro, and have firecrackers set off in his ass (Masashi Honda also did this, but Ezaki did it TWICE. The title of the match was even "Exploding Anus Match." YEAH damn). And that's just Ezaki! There are other arguably crazier wrestlers in the FMW (Atsushi Onita, for example) that probably exceed his blood-stained record of insanewickedawesomeness.
As for some good deathmatches, earlier I was watching an Exploding Octagon Cage match with Hayabusa and the Great Sasuke battling Tetsuhiro Kuroda and Mr. Gannosuke after weeks of turmoil and drama (GREAT match, very tense), and Hayabusa's classic match with Onita in the exploding timebomb barbwire cage match (which FMW invented, and as far as I'm concerned, perfected). I saw the barbwire-for-ropes match with Terry Funk and Tiger Jeet Singh the other day as well, and a Broken Glass Carribean Death match, and that was the shiz...
As far as a "pool match" though, I don't think I'm familiar with it. I stopped following FMW after Hayabusa's accident, so if it was in the two or three year span between the time he fell and FMW's bankruptcy, I probably haven't seen it. Do you have any more details about it?
