Anteaters. They're Just Crazy-lookin - S4-E23
Audio problem: In the episode with Enrique Iglesias, Charlie comes out to the deck to get his girlfriend and asks, "Isn't there something you could sand?" His lips say, "Isn't there something you could saw?"
Continuity mistake: When Alan comes into the kitchen singing his song, he reaches into the fridge and grabs a jug of orange juice. He then looks around the kitchen and sees that everybody seems to be in a bad mood. The jug of orange juice is gone and he is holding what looks like a jug of juice, but it had a screw lid on it and is full as if it has never been open. After talking for a few seconds the camera goes back to Alan and he is holding the jug of half empty orange juice again.
Character mistake: Jake's claim that a vomitorium was place for Romans to vomit is wrong and a common misconception. A vomitorium in reality is a passage in a stadium where a large number of people can exit at once.
A Live Woman of Proven Fertility - S4-E5
Continuity mistake: When Charlie films Herb on the deck, he says "Herb [3 second pause] you dumb bastard." When Judith watches the video there is no pause. (00:17:35 - 00:22:00)
I Merely Slept With a Commie - S4-E17
Continuity mistake: When Charlie is talking to his mum after meeting her new people, Evelyn's hand constantly changes position.
A Live Woman of Proven Fertility - S4-E5
Revealing mistake: When driving back from dropping Herb off at Judith's, there is a purple tinge to Alan's face from projecting the background.
Chosen answer: Alan might have thought the bra was too fancy to belong to a regular woman, "I'd love to meet the girl who filled this", he says. He assumed it was one of Charlie's many women.
