Continuity mistake: At the end of the episode "You Shook Me", Jackie is talking to a drunk Kitty who is putting mini umbrellas in Jackie's hair. The first shot of her doing this, she puts a green umbrella on the right side of Jackie's head. After Kitty asks for more umbrellas, the shot changes to Jackie which now has a pinkish, red umbrella on the right side and two green ones on the top.
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."
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.

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 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 then seen standing behind him.
Continuity mistake: When Kitty asks Red for a cat Red is reading a copy of Time magazine. He closes the magazine and puts it down on his knee while he tells her why he doesn't want a cat in the house but in the next shot the magazine is back in his hands and open to where it was before he closed it.
Continuity mistake: In the scene where Donna, Kelso, Eric, and Hyde are in The Hub after Eric gets suspended, Donna gets mad at the guys and leaves. But two shots later when Hyde is seen smiling and sipping his soda, you can see Donna's hair on the left side of the shot as if she was still sitting where she was before.
