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.
Somewhere I can live in peace with my friends. Don't you see? I have a mission to help pigeons everywhere. Wherever there's a bird in need of seed; I'll be there. Wherever there's a helpless flock suffering some abuse; I'll be there. Wherever there's a pigeon with a weak wing or a broken beak; I'll be there.
