Later, back at Castle Greyskull...
He-Man: ~sigh~ What is it now, skull guy?
Skeletor: I hereby challenge you to a battle of wits!
He-Man: Well that sounds simple enough. I could just shoot you with my missile launcher though. That way I'd be done with you and can get to fighting villains that stand a chance against me.
Skeletor: So, you're afraid are you? Don't think 'ol Dolph could outthink a rotting corpse, eh? Well I don?t blame you. I sure wouldn?t want to match wits with someone as massively intelligent as I, and another thing... I...
He-Man: Promise to shut up and I'll do it.
Skeletor: All right. Where is the poison? The battle of wits has begun. It ends when you choose and drink, and we find out who is right and who is going to be knocking boots with a sweet chick in your old bedroom.
He-Man: This is the stupidest thing you?ve ever tried, and that covers a lot of ground.
Skeletor: What do you mean?
He-Man: Do you really think I would fall for anything like this when there's only one glass? What kind of choice is that? If there's any poison it's obviously in the only container in front of me.
Skeletor: Well dammit, those things are heavy, especially when they're full. I didn't dare try and lift another one of them, I would have broken my spine, and being a dried out skeleton it's pretty brittle as it is.
He-Man: So you really thought just putting down a glass of tainted water in front of me was going to win you my castle?
Skeletor: It seemed like a good idea at the time.
