TV Quote from The Simpsons 08x06: A Milhouse Divided

Kirk: You're letting me go?
Cracker Factory Executive: Kirk, crackers are a family food, happy families. Maybe single people eat crackers, we don't know. Frankly, we don't want to know. It's a market we can do without.
Kirk: So, that's it after 20 years? "So long. Good luck?"
Cracker Factory Executive: I don't recall saying "good luck."
