Continuity mistake: From the outside of the house, you can see the staircase and door are to the far left of the house. But from inside the house, you have a fireplace and the staircase to the right of the door. So you know it's not the same house they use in the show.
Continuity mistake: During the scenes where they play Mortal Grandma (or whatever it's called), the characters' health bars don't change.
Continuity mistake: Carl says that Laura was five years old when the movie "The Wiz" was released, which was in 1978. That would mean Laura was born in 1973 and is or will be 24 years old. She only finished high school in the previous season.
Dream Date - S7-E22
Continuity mistake: Laura says that Steve asked her to be his prom date when they were six years old. In other episodes, she has mentioned that she first met him as a blind date - their date in the first season.
Continuity mistake: Whenever the characters in this sitcom fall through the roof, they end up on the living room floor. The house is a very conventional design with a second floor and an attic, so they should end up in the attic or on the second floor.
Who's Afraid of the Big Black Book? - S9-E5
Continuity mistake: Eddie's birthday appears to take place during the spring or summer. But the episode "Son" showed that he was born in January.
We're Going to Disney World (1) - S6-E22
Continuity mistake: In an earlier episode, Steve told Carl that he has to take charter flights because he was banned from all commercial airlines. Yet, in this episode, he takes a commercial airline to Florida.
Hot Wheels - S4-E12
Continuity mistake: Laura meets a guy named Ted supposedly for the first time. He is selling candy bars around the neighborhood and happens to knock on the Winslow family's door. Laura goes out on a date with him. However, Ted and Laura have already had several interactions, and have already dated and broken up in previous episodes in season 4.
Suggested correction: This is because the episodes were aired out of order. "Hot Wheels" was the 2nd episode produced for season 4 (production code 447802) and aired following the 15th and 13th produced episodes.
Continuity mistake: Carl tells the establishment's owner that Eddie and Waldo are under the age of twenty-one. However, in the episode "Best Years of Our Lives" (also Season 7), Waldo tells Maxine that he worked on a parade float every year in high school, which makes seven floats. If he failed three grades and started college in the previous season (with Eddie), he would be at least twenty-one years old by now - probably twenty-two.
Marriage 101 - S2-E3
Continuity mistake: Steve buys the ring for Laura at the end of their class project, then sells it to Carl as a gift for Harriet. Then when he proposes to Laura he says it's the same ring from that day.
Continuity mistake: The Winslows' front porch as seen from inside their house features a lattice wall with vines and furniture. However, establishing shots of the house show no such features.
Food, Lies and Videotape - S3-E17
Continuity mistake: Towards the beginning, Carl enters with a new video camera and we see a regular view of the scene mixed with POV shots from the camera as Carl narrates. When he's standing at the door with his bag, in the POV shots from the camera you can see that the door is open, but in the wide shots, it is closed.
