Hello HappyGirl and All,
I was just chuckling some on a trip down memory lane. You mentioned "Leave it to Beaver", and that's one show that dad wanted us to watch because it always contained good morals. Besides that, it was funny. There were many old television shows that helped to teach good morals. Those that didn't were at least clean and wholesome entertainment.
A few old shows crossed my mind:
Mr. Ed
My Three Sons
Ozzie and Harriet
I Love Lucy
The Honeymooners
Jack Benny
Ed Sullivan
for just a few... but let's at least list a game show or two
Queen for a Day
I remembered others, but I wasn't sure I had the names of the shows right. I'll end with listing some of my favorites.
The Three Stooges
Abbot and Costello
Laurel and Hardy
The Little Rascals
Dennis The Menace
Mr. Wizard
The Big Valley
The Lone Ranger
The Cisco Kid
Roy Rogers
Captain Kangaroo
The Marx Brothers
And YES, I liked the silent stuff -

The Keystone Cops
Harold Lloyd Shorts (I think this is right)
I know that DreamWeaver is going to have a ball talking about how old I am now, but I don't care. I thought the silent shows were hilarious. You could laugh your head off with just a few captions and some music playing in the background. As an example, the car chase scenes in the Keystone Cops were outlandish.
