The In-Laws (1979)

Continuity mistake: During the time when Vince and Sheldon are on the highway, in the cab fleeing the bad guys in Tijada , the same cars can be seen over and over again between shots.

Continuity mistake: When they land in Honduras, they are being shot at by the guys in the rocks. Right before they run to the car, they are laying along side of eachother. The camera angle changes and Vincent is now laying in the opposite direction.

Continuity mistake: When Sheldon goes to jump out of the plane, you can see him get the door open a few inches before they stop him. Seeing that they are about 10,000 ft. in the air, the door would have been ripped off instantly.

Vince Ricardo: Sometimes I'm so smart I scare myself.

Tommy: Dad and his mysterious phone calls.
Vince Ricardo: What the hell do you mean by that?
Tommy: Nothing. You're just always making these weird calls in back rooms and pay booths.
Vince Ricardo: You little snot-nose! Those phone calls put you through college.

Sheldon: There's no reason to shoot at me, I'm a dentist.
