As a kid I had the hots for many of the tv Moms : Barbara Billngsley ; June Lockhart ( on Lost In Space ) ; Mary Tyler Moore ( Van Dyke Show ) ; Donna Reed ...
June Lockhart was originally hot as Timmy's mom on "Lassie". I think she got divorced from Timmy's dad before she signed on to the crew of the Jupiter II back in the 60's.
