Also an Overly Long Gag, as he does one huge yell that goes on throughout the ending credits.
Sally's attempts to get Neil's attention away from "Terry": "Neil! Neil! NEIL!"
Smug Snake: Servo calls Talbot on this, saying he's got "built-in smug". It gets established from the very first shot of him, wearing an oily grin:
Mike: "Yes, I'M Dr. Paul Talbot, endocrinologist extraordinaire."
Stock Footage Failure: Discussed in-universe as the source of repeated jokes; the film does not hide its limited "African jungle" soundstage well, and the cutaways to broad wilderness just make it worse. Servo even points out the movie interspersing footage of alligators and crocodiles.
Crow: Boy, are they in Africa. Servo: Mm-hmm.

Crow: It's more like stock mileage at this point.
