Odo:
[Odo is buying the remains of a Ferengi from Quark] There is one thing I was curious about.

Quark:
And what's that?

Odo:
How do I know it's Plegg?

Quark:
It says so on the label.

Odo:
Isn't there some sort of letter of authenticity?

Quark:
The Ferengi Seal of Dismemberment is right here! What more do you want?

Odo:
I want Plegg!

Quark:
You've got him!

Odo:
Not if he's still alive.

Quark:
Still alive?

Odo:
Still alive.

Quark:
Plegg?

Odo:
After I tracked him down on Khosla II, told him about your little scheme, he was quite amused. [beat] I'm. Not.
