Arnold: What? This is awful, who did this?
Pigeon Man: People, Arnold
Arnold: We can rebuild the cages and sweep up. Your birds will come back!
Pigeon Man: Of course they'll come back, they're birds, I trust them. I understand them, it's people I don't understand. You see, Arnold, it's time for me to leave here. Some people are meant to be with people. And others, like me, are just... different
Arnold: Pigeon Man, wait.. none of this would've happened if I hadn't-
Pigeon Man: Arnold, don't be sad. You've taught me that some people can be trusted and I'll never forget that
