Was reviewing the Jetsons First Season DVD. In the Special Features, Janet Waldo provides commentary over the Rosie the Robot (1st) episode. In that commentary she mentions that she had never done cartoon voices until she did Judy. In the Tom and Jerry cartoon "Tot Watchers" (1958), the baby sitter sounds quite a bit like Janet Waldo. This speculation has also shown up in other threads. Any thoughts or info out there ??
