Continuity: In "The Unsinkable Mr. French" (season 5), the amount of whipped cream on Mr. French's jacket increases as he's getting up from the couch.

Visible crew/equipment: Oliver (a dog) jumps up on Uncle Bill's bed and starts barking at him. The real reason the dog is barking: in the shots of Oliver, the shadow of a towel or some sort of toy can be seen being waved around in order to agitate the animal. It even briefly pops into the shot a couple of times.

Other: Jane Webb is listed in the closing credits as "Store Lady". She actually played the "Story Lady".
