Piper Maru

Navy Officer: What the hell's that?
Mulder: It looks like the fuselage of a plane.
Scully: It's a North American P-51 Mustang.
Navy Officer: Yeah, it sure is.
Mulder: I just got very turned on.

Scully: They're afraid of you, of your relentlessness. 
        Because they know they could drop you off in the 
        middle of the desert and tell you 'The Truth 
        is out There' and you'd ask them for a shovel. 
Mulder: Is that what you really think of me? 
Scully: Well, maybe not a shovel, maybe a backhoe.
