Adrian Monk: Ah.
Natalie: No, w- Wait, what's wrong with that one?
Adrian Monk: The "K" went below the line.
Natalie: N- No, don't throw it away! Mr. Monk, please, I am begging you. We've been here for three hours. We've paid two bills.
Adrian Monk: I don't think the bank will take this.
Natalie: T- They'll cash it. l- I promise. If I'm wrong, I'll pay your water bill myself.
Adrian Monk: But, uh, let me just start over. I- I- It'll only take a minute. [Natalie takes the envelope and licks it] What are you doing, now?
Natalie: There you go.
Adrian Monk: Don't, don't, don't, don't!
Natalie: Too late. Already sealed it. Do you want it? You'll have to rip open the envelope. Good.
