I'm surprised that several people here feel that the "one foot on the floor" rule is a bad one. I respectfully disagree. I don't know how that rule originated, but I have an argument for why it should stay: It greatly reduces the risk of someone sitting on the cushion and causing damage to it.
A lot of casual pool players in the bars and poolhalls probably don't even realize that they could mess up the cushion like that, however, most of them do know the foot-on-floor rule, fortunately. I'm glad the IPT changed their rules to include this one. If they continued to leave that rule out and if it started catching on, eventually it might not be good for poolhall owners.
I don't think Danny was out of line for what he did. He didn't make the rules. I don't know why some are saying it is morally or ethically wrong to climb on the table. Its not unethical, any more than playing a masse or jump shot is. Yes, you can damage the equipment if you don't know what you're doing, or if you're not careful. Therefore, it is unethical to do it in a poolhall, for example, without permission. That doesn't apply here. He had permission. Its up to the people in charge to make the rules. Its up to the players to follow them.
Also, if a rule is left out by accident, and its brought to the attention of the officials, I don't understand what is stopping them from making an announcement that there was an error in the rule book and from this point forward such-and-such a rule is in effect. All this drama for nothing, in my opinion. At least we got RJ's funny song out of it.
Oh, and Johnny was out of line, IMO. Hopefully, it was just a reaction and he didn't really mean it. I'd assume that all the players felt a lot of pressure out there, and he might have just misdirected his frustrations with this unorthodox rule. It'd be nice if he would apologize to Danny for it, IMO.
