From “The Cartridge Family” episode of the Simpsons in which Homer Simpson buys a gun.
Oh, I don’t need anything like that… yet… Just give me my gun.
(He tries to take the gun.)
I’m sorry, but the law requires a five-day waiting period. We’ve got to run a background check.
Five days? But I’m mad now! I’d kill you if I had my gun.
Yeah, well you don’t.
(Homer walks out of the store, muttering.)
