Please identify this 1960s TV show/movie

I recall either a short-run comedic U.S. TV show (or possibly a TV movie) from the 1960s (maybe early 1970s) that featured a Brady Bunch-style family living in an old mansion/big house. I can’t remember more details than that, but I think I remember two elements of the show:

  1. The zany/wacky next-door neighbor used to use the window in the den/library to enter the house instead of walking through the front door;

  2. There was an episode/part of an episode that dealt with a “haunted” suit of armor walking the halls (IIRC, it was just a kid or a person stuck in the armor, but the family was getting scared).

I’m pretty sure it’s an obscure show/movie-- i.e., it’s not The Brady Bunch, Munsters, Addams Family, etc. It may have in fact been a failed pilot that ended up in syndication/rotation every now and then.

Help?

“Please Don’t Eat the Daisies”?

I don’t remember specifics like the neighbor coming through the den or the haunted suit of armor, but the first thing that comes to mind is “Please Don’t Eat the Daisys” (first a movie, then a TV show). I seem to recall them living in a big, old mansion.

The Ghost and Mrs. Muir?

Aha! Please Don’t Eat The Daisies. Thank you so much for figuring it out. . . a delightful little show, IIRC.

BTW, the episode with the knight’s armor-- “Night of Knights” sounds promising :-).
