Other mistake: Depending on the season the Bundys' address is 9764 Jeopardy Lane. Season 4 the address is 9674. But in the opening credits when Steve is shown on his porch the address is 9674. (00:00:20)
Revealing mistake: When the chain is cut from Al's wrist, you can see and hear that it's plastic not metal. (00:02:28)
Other mistake: Al eats a slice of pizza. But if you look in the box there's a small piece taken from the center of the pizza. He picked up a full size slice with crust.
Revealing mistake: Kelly is making popcorn on the stove. It starts popping even though the heat isn't even on.
Requiem for a Dead Briard - S10-E3
Continuity mistake: When Peg is comforting Kelly about Buck passing away, she is holding a bag that says "Petropolitan" on the front. The next shot when they go back to her, all a sudden the words are gone from the bag she is holding and Bud is holding a bag with those words.
Continuity mistake: After Kelly breaks the TV screen, each time the camera changes, the broken screen looks different each time.
Visible crew/equipment: Right after Jefferson walks out after saying what he was in jail for, when they are showing Bud and Al, you see a large head shadow go across Bud's leg from left to right.
Revealing mistake: When they blow up the scoreboard at first in slow motion, the entire scoreboard is blown up and destroyed. The next shot only a small portion at the top and middle is destroyed, not the entire thing.
Cheese, Cues and Blood - S6-E4
Continuity mistake: When Kelly shakes her head no to the guy she is playing for $10,000, he misses the shot and the ball stops at the far end of the table. When Kelly goes to take the next shot for the win, she is hitting the cue ball from the other side.
Deliberate mistake: Why would Al have his Polk High football uniform in England?
Suggested correction: Al cherishes his memories as a high school football player. It's quite possible that he takes the uniform with him on some trips, especially when going to another country. I've known people who do this with items that are important to them; i.e. a jewellery box or a favourite picture of family. They feel better keeping the item with them, in case something happens at home while they are away.
Peggy Loves Al, Yeah Yeah, Yeah - S2-E17
Other mistake: When Bud goes upstairs with his fake bag of "Valentines" (actually a bag filled with bottles), Kelly begins to look through some from her bag. Behind her, you can see David Faustino (Bud) purposely moving slowly up the stairs because Christina Applegate (Kelly) is about to find the envelope that is addressed to Bud.
You Gotta Know When to Fold 'Em (2) - S4-E17
Factual error: Bud and Kelly wouldn't be allowed to go in a casino in Vegas because they are both under 21.
Other mistake: When Peggy throws the final ball, all the pins fall except for one and the sweep bar comes down. It is then shown wobbling down without the sweep bar in play. This is an illegal drop and would not count under any PBA sanctioned tournament or in any bowling alley in the United States. The bowling alley would credit her with a 299, and Al would have a chance to get a 300.
Visible crew/equipment: When Marcy announces they only have time to grab their most precious personal possessions Kelly notes her own, and in the next shot the boom mic makes a happy appearance at the top of the screen. (00:07:45)
Revealing mistake: Marcy dries her dress in Peg's dryer. She comes downstairs with it on looking like it shrank. You can plainly see Marcy put on her belt and pulled up her dress to make it look shorter.
Factual error: Griff's shown being strapped into the electric chair. Problem is Illinois had stopped using the electric chair and switched over to lethal injection in 1983.
Other mistake: Al, Peg, and the kids go to the beach. Steve and Marcy are sitting not too far away from them, yet they never interact with each other. They had to see each other they just act like they don't notice each other.
Factual error: The sheriff does not come to your house and take your credit cards just because they are maxed out. The only time they would do that is if you stole someone else's card and were using it.
Sixteen Years and What Do You Get - S1-E6
Plot hole: Peg maxes out the credit card buying Al anniversary gifts and hiring a caterer. When Al tries to buy a watch for Peg it's declined. Later on Kelly somehow uses the credit card and is able to buy the expensive picture frame at the same store Al tried to buy the watch.
Continuity mistake: After Bud's Hail Baby, the spoon that had been to the right of Peggy's glass, changes position.
