Star Trek: Deep Space Nine, Season 3

Bashir:
Is there anything you need me to do while you're gone?

Garak:
Like what?

Bashir:
I don't know— Any unfinished business?

Garak:
Actually, Doctor, there is something. If you go into my quarters and examine the bulkhead next to the replicator, you'll notice there’s a false panel. Behind that panel is a compartment containing an isolinear rod. If I'm not back within 78 hours, I want you to take that rod and eat it.

Bashir:
Eat it?!

Garak:
Um-hum.

Bashir:
You're joking.

Garak:
Yes, Doctor, I am.

Bashir:
Very. Funny.

Garak:
I thought so! But the answer to your question, Doctor, is, “No. There is nothing you can do for me while I'm away.”
