Jessica's First Christmas - S2-E7
Deliberate mistake: Just before father O'Hara explains to Frank why he isn't in the nativity play he says to Betty "Perhaps I will have that cup of tea after all Mrs. Spencer" Betty goes to the kitchen but father O'Hara never gets his cup of tea.
Suggested correction: Perhaps Betty just forgot.
Moving House - S3-E1
Revealing mistake: At the beginning when Frank is directing the vans, we see that one gets its windscreen broken by a ladder from another van. However, the glass breaks just before the ladder touches it.
Betty: Don't get so depressed Frank, you've only been out of work two days. Mr Rogers hasn't worked for six months.
Frank: Mr Rogers is 86 years old!
Trivia: Michael Crawford performed all of his own stunts in this series.
