My God, You Are Serious

Leela: Doesn't it bother you even a little to be taking advantage of your girlfriend's trust?
Bender: Ah ha ha, ha ha ha! Oh wait, you're serious. Let me laugh even harder. HAHAHAHAHAHAHAHAHA!!

The inversion of I Was Just Joking. A character says something that sounds insane or absurd. Another character either laughs or snarks You Have Got to Be Kidding Me! — then realizes with alarm that the other character wasn't joking.

Expect to hear this phrase every time a Deadpan Snarker is confronted with the Zany Scheme of the week. Badasses who say things like "I'll just have to bust in and take them all out, then!" can usually expect this reaction, too.

If you agree to this, Grace asks you if you're serious; if you say yes, she disappears, and never comes back. The fourth payment is Annah's life (again, assuming she's actually in the room) and again, if you agree to this, Annah asks if you're serious. If you say yes, she becomes enraged and attacks you, fighting to the death. (The Pillar does not accept this as payment; accepting either of these payments slides the Nameless One's alignment towards evil.)
