Corrected entry: In the opening scene when they toast Eric stealing something he is holding his beer upside down.
Corrected entry: In the locker room, The Rock, playing father Rocky Johnson, uses the phrase "sports entertainment." That euphemism wasn't created until the 1990s.
Correction: It's intentional and a joke. Professional wrestling is "sports entertainment" as opposed to a "sport." I have always found the scene pretty humorous because of the phrasing. Besides which, there is no reason why Rocky cannot use the euphemism in the '70s. They are just words that he believes describes his business. It's not like he referred to a "laptop computer", something that would have been totally unknown in the 70s.
Corrected entry: In the opening scene, the boys are looking at a Playboy centerfold, circa 1976. However, the magazine is perfect bound, not saddle stitched (stapled) as Playboys were at that time.
Correction: It is not a Playboy. It is difficult to read the writing but it is definitely not a Playboy. In a later episode, Hyde is looking at a "Layboy". They didn't use the real magazines. Therefore, since it is "not" a Playboy, the binding is not a mistake.
A New Hope - S1-E20
Corrected entry: This is the only episode that doesn't use the theme song.
Correction: This was the FIRST episode to not use the theme song. There were several (at least 2 in Season 4 and 3 in Season 5) that didn't use the theme song. They just showed the credits over the action of the moment.
Stolen Car - S1-E14
Corrected entry: According to the official website, Point Place is a suburb of Green Bay, WI. Midge can't make meat loaf for Bob because she is taking a class at a community college in Kenosha, which is about 2.5 hours away from Green Bay. Kenosha gets mentioned in other episodes as well.
Correction: There may have been no place closer for Midge to take the classes she wanted. I would imagine "Woman Warriors" would not be a big curriculum item in the mid-70s at colleges. Even though 2.5 hours could be a bit excessive to drive, she could certainly do it. She is shown getting home very late at night. The other mentions of Kenosha never make notice that Kenosha is 5 minutes away or so - just that something is happening in Kenosha.
Corrected entry: At the 17 or 18 minute mark of the show, Hyde is doing dishes, Eric is behind him with a carton of milk, and Fez & Kelso sit at the counter as Kelso peels a banana. While Eric is griping that Hyde does too many chores around the house and makes him look bad to Red, Kelso takes a bite from that banana. You can plainly see that when he does this be breaks the banana, but when it cuts back a few scenes later, the banana isn't broken anymore.
Correction: The banana is still broken, the top part is just sitting flat against the break and the break is difficult to see.
Corrected entry: When Eric and Donna are on the hood of the Vista Cruiser, their heads go through the non-existent windshield.
Correction: There are views where you can see reflections off the windshield and you can also see them "propped" up by the windshield. The windshield is definitely there. The shot never cuts away from them so the windshield remains there. The "non-existant windshield" is, as stated, an optical illusion.
Corrected entry: When everyone is in the pool and Kelso convinces Jackie that having a party is a bonus - Jackie is the one who raises her arm in support instead of Kelso. You can tell as the sleeve is orange and Kelso is wearing a yellow armed shirt.
Correction: Look closer. Jackie is actually holding on to Kelso with her feet off the ground and both hands around his neck. When Kelso raises his hand, he picks up Jackie's arm a bit and you see some of the orange red of Jackie's shirt. However, it is definitely Kelso that raises his arm in a clenched fist. Jackie's hands are around Kelso's neck.
Thanksgiving - S1-E9
Corrected entry: In the scene where Eric and Kate kiss, Eric enters the room saying he needs something to sleep in and grabs something. But when he's leaving (after they've kissed) he leaves without the clothes he's grabbed.
Correction: After the "kiss" he had just gone through, it would not be unnatural for him to forget what he came in for - since it was obviously a convenient excuse to go into his bedroom. Also, who's to say, he didn't turn right around and get the clothes once he remembered.
Sunday, Bloody Sunday - S1-E10
Corrected entry: When Kitty goes into the basement and asks for a cigarette - the sleeve of the person that hands her one is red denim, which does not match that of any of the characters there. Hyde is holding a lighter, but wearing blue denim.
Correction: The sleeve is blue just like the denim sleeve that Hyde is wearing.
Sunday, Bloody Sunday - S1-E10
Corrected entry: This episode is supposed to be October 23, 1976 but the previous episode is Thanksgiving, which is in November.
Correction: Even though it was aired as the 10th episode, the official "That 70's Show" site list this as episode 5. It was broadcast out of order, not a mistake in the show.
Corrected entry: Before Kitty helps Red with selling appliances, Red blends some ice, but when he pours the ice into a glass they come out as ice cubes, not blended at all.
Correction: In the episode 'Eric's Buddy' it is revealed by Kitty and the audience, (as they laugh at Red) that he did not blend the ice very well and the cubes at the top did did not blend in the first place.
Corrected entry: Guys are sitting in basement, Fez is sent home by Red. While Kelso speaks, you can hear that Fez opens and closes doors. But in the next shot - Fez is standing in front of open door.
Correction: That sound is actually Red opening and shutting the door they use to get in and out of the basement, not Fez.
Corrected entry: In the scene where Eric is driving Grandma home, he tells her it wouldn't kill her to be nice and she dies. Eric realizes this and slams on the brakes. You can see Grandma's eyes open then close before she hits the dashboard.
Correction: Since we see no physical injuries nor signs of pain we must assume Grandma had a fatal heart attack or stroke, neither of which would have killed her instantly - though Eric would think she had died on the spot. Obviously she dies shortly after hitting the dashboard.
Corrected entry: In the scene where Kitty is making all the food because she is sad, she reaches into the oven and pulls out a tray of food. She doesn't even put on an oven mitt and she doesn't burn herself.
Correction: Many people place already prepared food in low temperature or turned off oven to keep the food warm. The oven is not at a temperature that would cause burns, so an oven mit is not necessary. Since Kitty was preparing a large amount of food, it makes sense that she would do this.
Punk Chick - S1-E22
Corrected entry: 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.
Correction: In "The Water Tower," everyone agrees that their pot leaf looks like a green hand giving the finger, then Kelso has his fall, so they might regard that as a failure and still be planning to do it right next time.
Correction: Believable character mistake.
