At the beginning of the episode, Tony tells Jeannie that his car is in the shop and he has to call a cab. Later, he rushes home, driving his car. He could've taken a cab to pick up the car. At the end of the story, they're about to go out to dinner, but Tony tells Jeannie that he forgot that his car is in the shop and has to call a cab -- but the car should've still been in the driveway when he rushed home earlier in the day.
Jeannie's feet can be seen when they are supposed to be vanished. After her feet had disappeared Jeannie and Tony were running to the bank, you can clearly see her feet.
As Tony pulls into his driveway and stops, his rear view mirror reflects one of the movie lights and it flashes into the camera.
