I don't know why, but playing D&D is making my group so much funnier than they have been before. We've been cranking out more good lines than normal. This is one of those epic, character-defining dialogues that so rarely happens.
Thief: Holy crap, you're a dragonborn.
Paladin 1: I am.
Thief: Is it true that dragonborn actually hatch from real dragon eggs?
Paladin 1: It is.
Thief: So then you're like, a retarded dragon?
Paladin 1: WHAT?!
Thief: If you were born from a real dragon egg, you should have been born as a real dragon, with wings and everything. But you're not. That seems like a birth defect to me.
Paladin 1: It isn't! I'm just a dragonborn!
Thief: Ha ha! You're a retarded dinosaur baby!
