Revealing mistake: When Harold and Albert are watching football on TV you only see the TV set from the back. If you look through the air vents you can see straight through it it - obviously a prop with no screen in it.
Revealing mistake: When Albert and Harold are fighting over the cracker Albert's face goes into the trifle, and if you look carefully we can see that he just lets go of the cracker and puts his head in the trifle deliberately.
Continuity mistake: At the end of this episode Harold picks up a knife and chases Albert round the table with the knife in his right hand, but when the door bell rings the knife has disappeared.
Suggested correction: The knife doesn't disappear he actually drops it if you listen carefully.
Visible crew/equipment: In the opening scenes where Harold is on the horse and cart in the shopping street you can see a crowd of people standing around watching the filming.
Visible crew/equipment: As the closing theme music starts playing, Albert and Harold pull a cracker. When they stand up while pulling the cracker, the boom mike is in shot above their heads.
