T-Rex: I've had a great idea! I'm going to convince one of my friends that I have a magical ring. But the catch is, the ring only works if you are pure of heart!
T-Rex: So, this friend of mine will undergo a regime of self-improvement!
T-Rex: However, when they finally have bettered themselves and are "pure of heart", they will realize that there was no magic ring: the magic was in them, all along!
Dromiceiomimus: But - that doesn't really make sense.
T-Rex: Sure it does! It's a magic ring!
Narrator: LATER...
Utahraptor: T-Rex, do you want to come over this evening to watch a movie?
T-Rex: Sure!
T-Rex: Actually, I was hoping I'd run into you. I have a MAGIC RING that I'd like to give to you! But the catch is, it only works if you are pure of heart.
Utahraptor: Oh - thanks, but nevermind. I had one of those before, and it turns out the magic was in me, all along.
T-Rex: Well, would-
T-Rex: Would you like another?
