Won't Get Fooled Again - S6-E13
Continuity mistake: When Eric bursts into the kitchen to tell Kitty and Red, who are sitting at the table, that Donna is not pregnant, the items on the table change position depending on the angle of the shots.
Who Are You - S6-E15
Factual error: In this episode, when Donna and Jackie are arguing about who is going to go outside, Jackie is seen holding a box of Chips Ahoy cookies. The logo seen on the box was used in the late 90s and early 2000s, rather that the logo used in the 1970s. (00:17:30)
Squeezebox - S6-E20
Continuity mistake: Kelso gets really close to Eric when he's trying to burn him about the other girl. The shot changes, and Kelso is further away.
Continuity mistake: After Eric's mishap with Donna's wedding dress, Kelso is in the Forman's driveway with the canoe (yes, a canoe), and the scarf around Kelso's neck changes repeatedly.
Character mistake: Kitty wants to reunite Bob and Midge together, saying it will reunite their only daughter. Bob has 3 daughters (just seen the younger one once). (00:12:30)
Let's Spend the Night Together - S7-E2
Factual error: After Kelso gets the call that his girlfriend's water had broken and runs out of the room, Fez answers the phone. In the background there are several license plates on the wall, one of which is an Indiana "Amber Waves of Grain" design, which was first issued in 1993.
Mother's Little Helper - S7-E7
Continuity mistake: When Kitty is showing Red "The Joy Of Sex" in the kitchen, the book goes from open to shut instantly between shots.
Character mistake: When Bob shows up in the driveway with the free calendar from Red's muffler shop, the calendar says "Foreman and Son." Their last name is spelled "Forman" without the E.
Continuity mistake: In the crowd scenes, Jackie comes back to her seat. A man sitting next to Donna looks at Jackie. The scene changes angles, and the man is looking straight.
Continuity mistake: When Donna introduces Sarah to the gang, she states that it took her 6 months of sorting records to become 'Hot Donna'. In season 3 episode 14 "Radio Daze" Donna has just started working there and gets the name 'Hot Donna' immediately. (00:01:20)
Factual error: Sizzling Sara is doing her live radio broadcast in front of a rack of magazines. One of the magazines is a Robin comic book. The series of Robin comics that used that logo began in 1993, 14 years after the episode takes place. (00:15:35)
Oh, Baby We Got a Good Thing Goin' - S7-E18
Continuity mistake: When Kelso is trying to get the baby to not cry, you can tell Bob covers its face to the camera so we don't see that it's not actually crying. Cut to a different angle, and the blanket surrounding the baby has moved. Cut back, and the blanket is covering the baby again.
Other mistake: Jackie comes out of her room while Fez has Caroline over, stating that she has to use the bathroom. However, in a previous episode, during Fez and Kelso's fight for the same room, it is the room that "has its own bathroom." (00:16:00)
Continuity mistake: When Fez knocks the clown over and shatters it, you see the head roll in front of the body and out of frame with the nose still attached. Donna then turns around and runs in to take the nose from behind the body of the clown.
Other mistake: When Bob comes to order from the clown, he gets told to go away since they're closed. He starts pulling away, but you can see he doesn't leave the frame quickly. The edge of the car is still visible when the gang is sneaking back over.
Good Old Fashioned Lover Boy - S8-E11
Continuity mistake: While St. Christine and Jackie speak about honesty, the brownies in Jackie's hand suddenly switch to Christine's hands in one shot, then return. (00:20:05)
Character mistake: Right after Hyde comes into the kitchen to get whipped cream for the stripper wife, Kitty Forman says "Kurt" instead of Red to Kurtwood Smith.
Suggested correction: She says, "Okay, what were you two talking about?". She doesn't use any name at all.
Factual error: When Donna and Randy are in Eric's bedroom, Randy is playing with Eric's toy lightsaber. However, the blade is green. No green lightsaber toys were produced until after the release of "Return of the Jedi", which occurred in 1983. Moreover, the handle is the modern style, not the vintage.
Continuity mistake: When Hyde enters the scene, his shirt is somewhat tucked behind his belt. In the following close-up shot his shirt is above the belt but returns to the tucked position in the next shot. (00:00:10)
Factual error: Fez wears a Sergio Valente pullover, which is a company not founded until 1981. (00:02:20)
