The second film
- Mort acting like a gremlin on the plane's wing, and being initially identified as one, in a reference to Nightmare at 20,000 Feet.
- Again to Planet of the Apes, when Skipper says he's so happy at the monkey he could kiss him. Monkey: "All right, but you're just so darned ugly." and casually smooches him, to Skipper's surprise.
