Barbara Eden; that's a grand episode and Jack Nicholson in two episodes. One where Aunt B was on the jury and Nicholson the defendant; and the second one where Opie and his friend find that baby; the couple included Jack Nicholson, both of these episodes were in color but a bit better.
Course my favorite Andy Griffith episodes include among others, the ones with Malcom Merriweather.
Oh, yes, I've been waiting for the Aunt Bee: Jury Holdout episode, but didn't remember that Jack Nicholson is in it--how fun!
Every crime forum I read or post in brings up that episode, with Aunt Bee as the "reasonable doubt" person. I know that she's right, in her case - but grrrr!
His girl friend in some of the first ones was Betty Anderson from "Father Knows Best." She is the owner of the drug store and is something of a feminist. I can see why it didn't work out, lol. That season has run twice and I just keep rooting for Helen to come to town!
They got stuck on Malcolm Merriweather a few months ago and had the rerun on 4 times in a row, so I saw a little too much of those, lol.
There was another one where an itinerant handy man came by and stayed to help do things around the house, but Andy always ended up doing them. Aunt Bee almost married the guy! He was the dad of all the girls on Petticoat Junction.
In the first few seasons, they only had a handful of "bad guys" - the same ones over and over. The main one was the blonde guy that played Sgt. Bilko's friend, I think Zimmerman, but might have that wrong.
