No, I don't think it's mere stupidity. I think Chris' handle on reality is nonexistent.
I explained it in another thread, but I'll repeat it here:
Some people think that Chris cutting his taint open was him being a dumbass, but they ultimately think it was just a drunk, spur-of-the-moment thing. Someone said "you're not a real woman" and Chris was like "I'll show you a real woman

" and grabbed the knife.
The reason why I don't believe that, and why I think it goes deeper, is because Chris had been rambling about his vagina growing in for at least a month, if not longer. He claimed to feel a lump in his crotch that he believed was his clitoris. He's incredibly dumb, and gullible, and little signs like that, signs that he's right, they go straight to his head.
Chris really did believe he had a vagina growing in.
In fact, I think he still believes it. He just thinks that maybe it needs more time to ripen or something. (

)
I think Chris has reached a level of stupid where reality doesn't matter. I don't think Chris is mentally capable of picking apart reality from fiction. I think he's diagnosable with something.
When Chris tips that rock or crystal or whatever in his hand and it falls forward, I think Chris gets excited because he thinks it really did fall forward via his mind. He's not capable of perceiving it any other way.
It's not Chris' fault he's insane. He needs to be under someone's care.
