Zelda was played by Sheila Kuehl who started her acting career long before Dobie Gillis she was only Four foot ten. Years later she went to Harvard Law got into politics an got into Calif assembly and Senate...she was hard core leftist an feminist she was openly out on gay issues an kinda focused on that in Santa Monica area. I think shes still alive at 80.

Another unattractive lesbian and man hater who could not ever get a date.
No doubt she strapped it on and hard.
