Dick: Can I ask you something, sir?
Big Giant Head: Well, sure, son.
Dick: Why did you wait until now to tell me you're my father?
Big Giant Head: Well, I've been very busy. But now... I want to find new meaning in my life. And please call me dad.
Dick: I couldn't do that, not after eons of you being my unpredictable and domineering overlord.
Big Giant Head: That's a short leap to dad.
