Jim Parker: Isn't that - water up ahead?
David Herdeg: No. This is a desert. And that's a mirage.
Jim Parker: [later, walking through the flooded plain] How much longer you think this mirage is gonna last?
[Trying to steal Allison's car]
David Herdeg: Where the hell's the clutch?
Allison Hayes: It's automatic!
David Herdeg: Get in, you're driving.
David Herdeg: [sees President Ronald Reagan giving a speech on television] Hey, I know this guy. Is this another movie?
Allison Hayes: [smiles] No, David, it's not another movie.
Sheriff Bates: We've all got problems, honey. But we don't solve 'em with guns.
Major Clark: So, what did you think of the future?
David Herdeg: Television was great.
Major Clark: You didn't see enough of it.
David Herdeg: [to transvestite] What the hell are you dressed like that for?
David Herdeg: This now, this time, it's not ours. We weren't here when it happened. The experiment took place on a ship in a Philadelphia harbor. It was - 1943, October. Does this sound... crazy? You know, or is this sort of thing possible now?
Sailor #1: Hey, there goes the whiz kid.
Sailor #2: Doesn't look too happy, does he?
David Herdeg: Maybe he knows somethin' we don't.
Sailor #1: Thanks, David, that's just what I wanted to hear.
David Herdeg: Whew. What is *that*?
Allison Hayes: Oh, I think it's a Porsche.
David Herdeg: Now that's *really* neat.
David Herdeg: You know, I got it all figured out... Navy owes me 40 years back pay.
Allison Hayes: Why'd you join the Navy?
David Herdeg: You know the old saying: girl in every port.
David Herdeg: What the hell have you done, Longstreet?
