Kids in the Back Seat

Anybody who has ever had to drive anywhere with kids in the back seat can appreciate this dialogue. Just picture Jason as "Daddy", Gwen as "Mommy", Alexander as "the older brother" and Guy as "the younger brother" and see how it fits with your experiences.

Guy Fleegman: I changed my mind. I wanna go back.
Sir Alexander Dane: After the fuss you made about getting left behind?
Guy Fleegman: Yeah, but that's when I thought I was the crewman that stays on the ship, and something is up there, and it kills me. But now I'm thinking I'm the guy who gets killed by some monster five minutes after we land on the planet.
Jason Nesmith: You're not gonna die on the planet, Guy.
Guy Fleegman: I'm not? Then what's my last name?
Jason Nesmith: It's, uh, uh - -I don't know.
Guy Fleegman: Nobody knows. Do you know why? Because my character isn't important enough for a last name, because I'm gonna die five minutes in.
Gwen DeMarco: Guy, you have a last name.
Guy Fleegman: DO I? DO I? For all you know, I'm "Crewman Number Six"! Mommy... mommy...
Sir Alexander Dane: Are we there yet?
