- April: Sean, whatever you do, don't ask her for any help during this trip. She's dumber than a box of rocks.
- Sean: Gotcha.
- April: Anyone who doesn't know that a Parsec is a measure of distance, shouldn't be in on this mission. Not even as a bumbling bureaucrat.
- Sean: So, what career would you recommend for her?
- April: I dunno. Writing Sci-Fi screenplays?
- Sean: Who are you? Whaddya want?
- Ebb Melchior: My name is Ebb.
- Sean: Ebb? How do ya spell that?
- Ebb Melchior: E-B-B. Sometimes we pronounce it with just one B, for short.
- Agent Y: Are you making this up? It sounds pretty incredible.
- Professor Johnson: You guys are about to launch a backyard rocket to Mars, and you're worried about credulity? By the way, if you wanna pass as an ordinary American, you have to say Nucular, not Nuclear.
- Sean: What do you think we'll find there?
- April: I don't know. Maybe nothing. Maybe something really scary.
- Sean: Scarier than the Professor's giant crabs?
- April: Sure. Giant bat-rat-spidercrabs. Giant man-eating plants. Boy, I'm glad I'm not a man.
- Sean: Giant amoebas.
- April: Amoebae.
- Sean: Nobody says Amoebae.
- April: Are you calling me a Nobody?
