In the second segment, while the old men are watching the Jeopardy episode, the female contestant gives a correct answer to a $50 question. Her score increases from $90 to $140, however the host says "Correct for $500", adding an extra $450 to her total while the numbers displayed don't match up.
In Segment #2, when Leo Conroy (played by Bill Quinn) is standing outside saying goodbye to his family, he is seen from behind, holding two suitcases. On the sidewalk, near the arch, there is an object, possibly a can. After his family leaves, there is another shot of him from behind, but the object has disappeared.
An exterior shot of the airplane in Segment #4 shows the landing gear to be in the down position. The pilot later comments that the plane would be landing in twenty minutes, far too long for gear to be down prior to touchdown.
