[a ghostly Moe appears in the hotel's bar]
Moe Szyslak : So, what'll it be, Homer?
Homer Simpson : Moe, gimme a beer!
Moe Szyslak : No. Not unless you kill your family.
Homer Simpson : Why should I kill my family?
Moe Szyslak : Uh, they'd be much happier as ghosts.
Homer Simpson : You don't look so happy.
Moe Szyslak : Oh, I'm happy! I'm very happy! La-la-la-la-la-la-la! See? Now waste your family, I'll give you a beer!
