I'm pretty sure they were drunk during that match. I've seen the entire show, and all-throughout you can see the Briscoes in the background near where the wrestlers make their entrances, and they are drinking from cups.
Not only that, but the main event was a tag team deathmatch, Homeless Jimmy & Hellaware Assassin vs Mad Man Pondo & Brain Damage, and Jay Briscoe decided to follow Damage and Pondo out to the ring in a manager role. He eventually made it into the ring, and he completely no-sold a bunch of lighttube shots....seriously, Jay Briscoe just stood there, covered in blood and glass, and didn't move.
The whole show was weird anyway, especially considering that it took place in someones driveway.
