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)
Visible crew/equipment: In the scene in Bargain Bob's where Donna is talking to Bob, the end of the set and lights can be seen in the reflection of metal cookware that Bob is tying balloons to. (00:07:50)
Punk Chick - S1-E22
Other mistake: Jackie and Kitty are baking a pie in the kitchen and Kelso walks in. Jackie and Kelso have an awkward encounter as if they are separated, but they got back together at prom.
Thanksgiving - S1-E9
Factual error: The scene where Kitty is making peanut butter celery for Thanksgiving appetizers; she is using Skippy brand peanut butter and the packaging is not from the 70's, it's the current packaging. (00:05:10 - 00:06:05)
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.
Punk Chick - S1-E22
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."
Punk Chick - S1-E22
Revealing mistake: While cuddling in the car Donna tells her boyfriend that she isn't wearing a bra when it is obvious that she is - at one stage when she leans toward him her sweater tightens across her back and the shoulder strap and clasp of her bra is outlined.
Visible crew/equipment: When Jackie tells Eric that she can really use a friend right now, in the next shot facing Eric just as he says, "Okay, well, good luck with that," the camera and crew member wearing a blue shirt can be seen at the left side of the screen. (00:01:00)
Prom Night - S1-E19
Factual error: In the scene where Kitty and Midge are talking about work there is a box of Krispy Kreme doughnuts on the counter. The logo that is on the box was not used on Krispy Kreme boxes until the mid 80's.
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.
Character mistake: Fez clams that he has never seen snow before, however this episode takes place January '77. there have been episodes with snow that date earlier, eg. "The Best Christmas Ever" which had snow in the background of the set.
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.
Factual error: Red takes the gang to a World Wrestling Federation event; in the '70s, it was the World Wide Wrestling Federation.
Visible crew/equipment: When Donna and Eric run to the car to discuss something secretly, a camera can be seen entering the right side of the scene. (00:01:55)
Visible crew/equipment: As Jackie opens the door and comes into the room near the end, you can see the bottom of a microphone. (00:20:15)
Visible crew/equipment: Stage lights and the end of the set can be seen in the scene when Kelso is confronting another man for courting Jackie. (00:16:00)
Visible crew/equipment: When Kelso sees Jackie in the hallway at the rally, he walks over to her. As he does this, the shadow of the camera is visible on the lower half of his coat.
