Here's something I didn't know about the Beetle comic strip:

In 1954, Beetle and several of his friends made a two-week visit to Beetle's sister, Lois. They were soon back at Camp Swampy, but Lois and her family were spun off into a strip of their own — Hi and Lois, written by Walker and drawn by Dik Browne (who, incidentally, inspired the character "Plato").

I believe "Hi and Lois" is still around as well, maybe even in the Arizona funny papers?
