The actor in this picture was the first Ward Cleaver.
He's a cannon dealer now.
Wow, missed that.
I like looking for things in each episode that I never noticed before. For me it makes watching the show (over and over ad infinitum) more interesting. Here are a few I found:
In some episodes the water crock in the jail is missing
In at least two episodes the coffee pot in the back room of the jail doesn't have a lid. They use a saucer plate to cover it.
When a local is in the jail the keys are left on the peg between the cells. When someone from out of town is locked up the keys are put in the desk drawer (except for the time Barney forgot in S3:E32 "The Bighouse").
Although Walker's Drug Store sells pipe tobacco, no business in Mayberry sells cigarettes, cigars or snuff even though they are often used or mentioned in the show. Maybe Andy and Mr. Goss buy their smokes in Mt. Pilot.
When Frankie Flint goes to the drug store to get some tobacco for her pa, she doesn't specify pipe tobacco or
snuff. I always thought it was snuff.
Correction: Frankie Flint asks for chawin' tobacco for her pa in Walker's drugstore.
As to the water crock, in one episode Barney serves water from a pitcher,
It was probably just the lightin'
- like Andy said
