The Nostalgia Critic does not say his opening catchphrase, but he does sing the ending catchphrase.
Nostalgia Critic: (meeting an older version of himself) Where am I?
Older Nostalgia Critic: You are inside the bad movie. A film so horrible, it actually ages you even as you watch yourself.
Nostalgia Critic: Wow! The movie's that bad?
Older Nostalgia Critic: Yes, now piss off! (throws a piece of bread at the Nostalgia Critic, knocking him out) I'm trying to eat my processed cereal. (gets hit from behind by another piece of bread)
Even Older Nostalgia Critic: Would you shut up? I'm trying to die over here for crying out loud!
