Droopy:
[narrating] Once upon a time, there lived a king and all of his people. No one, not even the king, dared to leave the castle, because of a terrible dragon that lived in a nearby cave. In desperation, the king issued a proclamation: "To whomever shall rid our land of this terrible dragon I offer the hand of my beautiful daughter, the princess." Of all the king's knights, only two were brave enough to face the dragon, Sir Butchalot and Sir Droopalot. And so the two brave knight set forth to win the hand of the beautiful princess.

Droopy:
[to the dragon] I'm gonna slay you, and I'm gonna marry the princess.
