Also, Doris Packer, who played the principal (Mrs. Rayburn) at Beaver’s school also played the mother of Chatsworth Osborne Jr from Dobie Gillis Show. Also Mrs. Fenwick on the Beverly Hillbillies.
And Madge Blake, who played Larry Mondello’s mother later played the part of Aunt Harriet on the Batman television show.
Yeah, I like to joke that Batman and Larry Mondello are cousins.
Madge Blake was related to Milburn Stone.
