Which actors/actresses from other tv series do you recall seeing on Dennis The Menace? And who are your fav's?

Jean Stapleton (Edith on All in the Family) as The Wilson's temporary housekeeper - I think she was the biggest surprise.

Ronny Howard (Opie on The Andy Griffith Show) played Stewart, in early episodes, the year before being cast as Opie Taylor.

Katherine Card (Mrs. McGillicuddy on I Love Lucy) appeared as a woman outside the drugstore.

Alice Pearce - (Mrs. Kravitz on Bewitched) as Mrs. Tarbell, a friend of Miss Cathcart

were some of my favorite appearances.
