Wanda Li: [ghostly, as Arnold is about to eat Ralphie's mallowblaster] Arrrnollllllld...
Arnold Perlstein: Huh? I've heard my stomach growl before, but - talk?
Wanda Li: Arrrrrrrnollllllld - are *you* about to eat Ralphie's mallowblasterrrr?
Arnold Perlstein: Uh, no... I-I mean, yes! Eeeee! Wait a second! Who *is* this?

Arnold Perlstein: Not hungry? But I could eat a...
Wanda Li: You just *think* you're hungry, but what you *really* are is - thirsty.
Arnold Perlstein: I am?

Wanda Li: Look, I'm your conscience, all right? Just do what I say and drink the seltzer. Now!
Arnold Perlstein: [to Liz] Time me.
