Failure to hit an orc is not an action. You can try again.
Attacking an orc is an action. Failure to attack an orc is not an action.
DM: The ogre attempts to push you down as you rise. Roll a Reflex save.
BOB: A "2". Dang.
Oh, I see. You're equivocating on "failure".

fail⋅ure
–noun
1. an act or instance of failing or proving unsuccessful; lack of success: His effort ended in failure. The campaign was a failure.
2. nonperformance of something due, required, or expected: a failure to do what one has promised; a failure to appear.
3. etc.
I intended #2 in the text you quoted, and you're reading me as intending #1. Nonperformance, then. Bob attempts to perform the "standing from prone" action, which uses his move action. The ogre prevents him from doing so (apparently using some sort of immediate interrupt power). Bob remains prone. Had Bob been unconscious, he would not have been able to use his move action to attempt to perform the "standing from prone" action, would not have triggered the ogre's power, and the ogre would still have an immediate action left that round.
Could you perhaps not read my posts in the most ridiculous fashion you can come up with? That's certainly a good way to not see any sense in what I'm writing, but it's also a very poor way to conduct a conversation. Of course, it appears to me that the entire problem here is that you're attempting to construe not just my posts, but the 4e rules, in the most ridiculous fashion you can come up with, rather than doing what most of us are doing, and creating our narratives in a way that make sense, rather than trying to demonstrate that the rules are silly because we can contrive silly interpretations of them. It does not bother me if it is merely possible for bizarre explanations to be created for the results of the game mechanics. It would bother me if it were necessary, but it is not. That it is possible is a point rendered moot when a group of players sits down to a table and decides that unconscious people should not be allowed to tap dance.
I think that perhaps we have indeed gone as far as we're going to with this, considering that you're now simply trying to make fun of things I have posted without giving them a considerate read.
