I Found Your Moustache - S7-E17
Character mistake: Charlie mentions Alan's 1989 Volvo. Actually it is a 2nd generation Volvo V70, built between 2000 and 2007.
Ixnay on the Oggie Day - S7-E18
Revealing mistake: Charlie turns the money he's holding toward the camera, making it too obvious that it's prop money and not real.
Continuity mistake: Towards the end of the episode, Alan and Jake return to their hotel room with a bucket of chicken and sit side by side. Once they start talking about opening a restaurant and naming it, the bucket gets noticeably closer to Alan's left arm between cuts from him to Jake.
Hookers, Hookers, Hookers - S8-E4
Character mistake: Gordon says that he never had sex with anyone Alan knows, yet in Season 3 he briefly dated Rose and according to Rose also had sex with her.
Dead from the Waist Down - S8-E11
Continuity mistake: In this episode Alan says that he gave Judith diamond earrings while out, and that she filed for divorce then kicked him out and he moved in with Charlie. However, at the start, Alan is kicked out, and it's several months later that Judith files for divorce as he receives the papers and it's a plot point in that episode (S1 E8).
Dead from the Waist Down - S8-E11
Factual error: Alan and Lyndsey are playing scrabble. Alan is shown laying tiles down horizontally, and claims that he is using the "Z" on a triple letter score, and the "I" on a double word score, changing "it" to "ziti". This is impossible on a normal Scrabble board - those multiplier squares are all offset from each other except one row, and then they're five squares apart.
Skunk, Dog Crap and Ketchup - S8-E13
Factual error: Despite Alan's general bad luck he indeed wouldn't have to be afraid of the skunks. In reality skunks use their anal scent glands very reluctantly and only if they feel threatened because they only carry a limited amount of liquid and have a rather long "recharging" time. To that effect a skunk that apparently feels home in a suburban surrounding would never feel threatened by a human.
Factual error: Walden's Skype rings as if it was Bridget who called him, but it is obviously the other way around.
The Squat and the Hover - S9-E6
Continuity mistake: Jake states that when Allen got the divorce papers he was on a boat. However it is shown that Jake was in school. (00:02:00)
The Squat and the Hover - S9-E6
Continuity mistake: The box that Allan puts on the sofa in the pre-credit sequence is constantly changing position. Note the tape and labels. (00:03:40)
The War Against Gingivitis - S9-E18
Continuity mistake: At the beginning after Waldon's ex-wife video calls Waldon about Billy, Waldon goes outside to the balcony and screams. When Waldon screams, there's a cut to Alan by the sink where he also screams, breaks a plate and drops a green towel on the floor. The next cut after Alan, is Waldon coming back inside and Alan asking "Are you all right?" Look in the background and the green towel is all of a sudden folded and hanging on the side of the sink.
Avoid the Chinese Mustard - S10-E7
Continuity mistake: When Missi and Walden are sitting at the kitchen table, discussing what being in love feels like, Missi reaches across the table and places her right hand on Walden's right hand. The shot changes to a different angle, and now it's Missi's left hand that is on Walden's right hand. They switch back to the original angle, and it's her right hand back on his hand again. The tattoo on her left inner forearm immediately gives it away. (00:18:00)
This Unblessed Biscuit - S11-E3
Continuity mistake: When Alan is explaining the cup situation to Walden, the position of the cup on the table changes instantly.
Chosen answer: No. It's very similar, but not the same set.
