From "The Golden Palace: It's Beginning to Look a Lot (Less) Like Christmas (#1.12)"
[a group of recently-divorced people staying at the hotel have demanded all reminders of Christmas be removed
] Well, the tree's in the dumpster and I feel like a million bucks. Ha, ha. This is gonna be the best Christmas ever, huh? No caroling, no gifts, no dinner to clean up afterwards. No reminders of Christmas whatsoever.
Ah, 'scuse me, didn't you forget to say 'Bah, humbug'?
[really getting enthusiastic
] So I did! Bah, humbug. Hah, hah, hah. Bah, humbug.
Chuy, every time you say 'Bah, humbug', an elf cries.
