Been watching this for well over a week on LiveTV. It ran for seven seasons surpassing the Andy Griffith Show in episodes and many of the same actors appear in episodes of both series including Francis Bavier (Bee), Robert Emhardt (stranger in a hurry), Howard McNear (Floyd), Joanna Moore (outshoots Andy), Mary Grace Canfield (Thelma Lou's cousin), Josie Lloyd (niece to Helen?), Howard Morris (Ernest T.), Michael J. Pollard (cousin Virgil) and Ellen Corby, (head of theft ring)
Naturally the stories are well dated, some very good, others just lame but they were very entertaining when they were first introduced and it's an easy watch at bedtime.
Others of note: Brian Keith, Peter Falk, Alan Napier, Raymond Bailey, Dick York, Walter Matthau and many others you will no doubt recognize.
