Can you name any long running shows that didn’t feature a Halloween themed episode?

Some shows have one every year, but there are others –I believe Seinfeld is one- that never had even one.

One day at a time, Brady Bunch ( surprisingly being it was a kid's show)

Three's Company
Diff'rent Strokes

Andy Griffith Show??

One day at a time, Brady Bunch ( surprisingly being it was a kid's show)

That Brady Bunch episode where everybody tried to scare each other first aired on Oct. 27. I bet it was advertised as being Halloween-ish

The Donna Reed Show -- there are several "spooky" episodes but none that address Halloween specifically. But that seems to be true of many popular shows of the time.

Halloween specific shows: Bewitched (5), The Beverly Hillbillies, Happy Days, The Munsters, The Addams Family, My Three Sons, Cheers

Spooky for Halloween season shows: I Dream of Jeannie, Donna Reed, Leave it to Beaver, Green Acres, Gilligan's Island, The Brady Bunch, The Monkees, Wonder Woman, Superman, Gidget, Dick Van Dyke, Andy Griffith, Laverne and Shirley, I Love Lucy, Petticoat Junction, etc.

Not sure: Family Affair, Get Smart, That Girl, Mary Tyler Moore

Then of course there was Dark Shadows where every day might as well have been Halloween!

The Donna Reed Show -- there are several "spooky" episodes but none that address Halloween specifically. But that seems to be true of many popular shows of the time.

Yes, there are at least three Father Knows Best episodes that would qualify--Mr.Beal Meets His Match, Formula For Happiness, and The Great Anderson Mystery,
