Continuity: In the scene where Eric gets the keys to the Vista Cruiser, when Red and Kitty leave the room, you can see that the door to the living room is wide open, but before when they were telling him the responsibilites of owning a car, it is closed. No one had gone through the door during the entire scene.

Continuity: When Red throws the keys to the Vista Cruiser to Eric, you can see he (Eric) catches them with both hands clasped together, then the camera cuts to show Red and Kitty (with the back of Eric's head) you see now that his right hand is clenched in the air, then it cuts again and his hands are clasped together again. He could not have moved his hands that quick.

Factual error: Red takes the gang to a World Wrestling Federation event; in the '70s, it was the World Wide Wrestling Federation

Continuity: This episode was supposed to air before 22 (1x22) "The Water Tower", because in this episode where Eric tries to talk some sense into Hyde about moving to NY he speaks of "we were going to paint a pot-leaf on the water-tower" something they already did in the episode before.

Continuity: In the scene where Kelso enters Jackie's room (the second time) when she is sick, she throws the teddy bear at the door. When Kelso enters there is a shot of the bear in front of him at his feet. The scene changes to only show him from the waist up (he never moves) and then changes to a longer shot where he is still seen. The bear, once at his feet, is nowhere to be seen. The shot then changes to Jackie and back to the longer shot of Kelso. The bear is now behind Kelso's feet.
