Clients love to use the word "Broken" (or synonymous word).

Client: The program is broken. Fix it ASAP.

Me: Ok, give me some details so I can help you.

Client: No, fix it. *Becomes an ass*

Me: Alrighty then, let me sit here doing nothing for a couple of hours. Then say that I tested the code against your original request, and it's working as intended.

Client: Sounds good.

(Pretty sure that's how it went)
