I normally don't like Zoidberg that much, but in this episode he's really shining.
[Scene: Observation Room. The general and the man stand behind a one-way mirror in a room filled with computers and other equipment.]
Man: This experiment will determine what food, if any, the alien eats.
[Cut to: Clean Room. Zoidberg enters back to front. He turns around and sees the food on a table.]
Zoidberg: A buffet! Oh, if only I had my wallet with me!
[Cut to: Observation Room. The man presses an intercom.]
Man: Um, it's free.
[Zoidberg squeals and gorges on the food. It splatters up against the mirror. The men peer into the room and recoil in horror as Zoidberg splatters himself against the window and licks the food off.]
General: Get me the President.
[Scene: Interrogation Room. Zoidberg is tied to a chair. Truman sits opposite him with the general and other man behind him.]
Truman: If you come in peace, surrender or be destroyed. If you're here to make war, we surrender.
Zoidberg: Both good. The important thing is I'm meeting new people.
Truman: Bushwah! Now what's your mission? Are you planning to make some kind of alien-human hybrid?
Zoidberg: Are you coming onto me?
Truman: Hot crackers! I take exception to that!
Zoidberg: (sexfully) I'm not hearing a no.
[Truman stands up.]
Truman: Nerks to this space crab! If we want information, we'll have to do us an old-fashioned alien autopsy!
[A man holds up a saw behind Zoidberg. Zoidberg turns around.]
Zoidberg: Hooray!
