Gourmet Night (a.k.a. Gourmet's Paradise) - S1-E5
Revealing mistake: When the Colonel first meets Basil, the same shot is used twice of the Colonel twitching.
Other mistake: During the hold up when Medhurst is sprung from the police van, the breakdown truck used to pull the doors of the van reverses towards the police van twice after releasing the chains off the doors before driving away, and the camera lights are reflected in the side of the white getaway car.
Factual error: Ann enters Julie/Barbara's room and Eton John's "Rocket Man" is playing. Barbara is siting in front of the turntable playing a 33 LP that has the distinctive Atlantic Records Red/White/Green label. Rocket Man was never published on Atlantic records. (00:19:00 - 00:20:00)
Other mistake: Season 50, Episode 5: During the 'Family Bonds' skit, the presenter says the show was about a single father raising two daughters, but in the clips, it's a son and a daughter.
Continuity mistake: Conchita slaps Cash across the left cheek, which he's rubbing as he returns to his office. In the next shot, as he comes through the door, he's rubbing his right cheek instead.
