Visible crew/equipment: After Opie tells Ellie everything that Andy told Aunt Bee, Ellie tells Opie that she's on the trail of a baboon, and when it cuts to the next shot of Ellie coming down the stairs we can see the chalk T-mark on the floor where she stands.
Continuity mistake: Wilma opens the bedroom door to find Fred covered in flour, but in the next shot the bedroom door has vanished while Fred stands in the doorway.
Same Picture, Different Frame - S4-E2
Continuity mistake: While Morgan is driving she gets a flat tire, and in the close-up the Cadillac's license plate number is 84-I33, but in the wide shot it's 5G6-420. (00:09:20)
Other mistake: The opening credits on the first ever episode of Coronation Street in 1960 give the copyright year in Roman numerals as MCMLXIX, which is 1969, and not MMX, which is 1960. (00:00:01)
