Smithers: Oh my God! I knew I shouldn't have left..

Smithers: Oh my God! I knew I shouldn't have left...
Burns: Ah, welcome back Smithers. Say, do you know Homer Simpson, he
pitched in around the office while you were away. Bang-up
job, Simpson, but I guess it's back to your trusty post in
sector 7-G.
Smithers: [sighs in relief] You heard the man, Simpson.
Burns: Ah, and my dear dear Smithers. You're no longer needed at
all.
You're fired. Ta!
Homer: [to Smithers] *You* shouldn't have gone away in vacation.
-- Then who'll release the hounds?, "Homer the Smithers"
