Homer: Thanks for giving me my old job back.
Burns: I'm afraid it's not that simple. As punishment for your

Smithers: Uh, sir, that's the plaque.
Burns: Ah yes, the special demotivational plaque to break what's left
of your spirit. Because, you see, you're here forever.
[Smithers screws a "Don't forget: you're here forever" plaque
into the wall]
Burns: Don't forget: you're here forever!
