Anytime I change Finn's diaper he says the same thing, almost exactly word for word, every time:
Finn: It's not fun to be a bunny. It's fun to be a BOY. I don't want to be a bunny! I want to be a boy! Bunny's don't have fun. Only boys have fun.
Each time. Without fail, these days, at least.
How on earth he came to equate diaper changes with contemplating his humanity, and the wretchedness of those bunnies, I'll never know. ;)
