Continuity mistake: 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.
Continuity mistake: In the scene where Eric gets the keys to the Vista Cruiser, just after he catches them, you can see that the door to the living room is wide open, but before when Red and Kitty were telling him the responsibilities of owning a car, it is closed. No one had gone through the door during the entire scene.
Continuity mistake: When Eric is at the pharmacy, Bob picks up a bottle of cologne. When the shot switches so does the bottle of cologne.
Continuity mistake: When Kitty comes downstairs to give the gang cookies, she tells Eric that she picked out an outfit for him to wear on career day. He then turns and mouths the words "Help me." In the next shot you can see Jackie sitting on Kelso's lap when in the previous episode, she broke up with him. In the next shot she is standing behind him. (00:01:00)

Continuity mistake: When Eric and Hyde are talking, while on Hyde's front porch, they talk about painting a pot leaf on the Water Tower before Hyde leaves to New York, but they already did it in the previous episode, "The Water Tower." (00:17:35)
Suggested correction: This episode (production code 120) was filmed before the "Water Tower" episode (production code 123). It was just aired out of order. If you watch it in the right order, there is no mistake.
Suggested correction: Eric said, "Do you remember when we painted the pot leaf on the Water Tower?" Hyde said, "Vandalism isn't a good reason to stay." Eric said, "We wouldn't do it without him, meaning vandalism."
That's not what was said at all. Eric said, "Remember? We were gonna paint that pot leaf on the Water Tower?" Hyde then says, "You can do that without me."
Continuity mistake: 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.
