Your idea is bad and you should feel bad.
Well, I don't. :biggrin.gif:
In seriousness, though, why put yourself (or anyone else) through the misery that is playing Minecraft in 3rd person? There are currently plenty of pointless days (Talk Like A Pirate Day for example) but they are generally a bit of fun as opposed to a form of torture.
First of all, like I said at least 3 times before, you would HAVE to do it. If you wanted to you could. And it could be fun if you stop complaining about it. It'd be more of a challenge to do stuff and that's the point. And besides, you wouldn't HAVE to do it the whole day. You could quite at any time, I suppose.
