Lost in Space
My Friend, Mr. Nobody
While wandering around the planet, Penny (Angela Cartwright) comes across a strange-looking grotto and a deep cave, where dwells a talking disembodied life force. When Penny reports this finding to her parents, they dismiss it as a figment of Penny's imagination. Before long, however, Penny's "imaginary friend" proves all too real, thanks to the interference of the pesky Dr. Smith (Jonathan Harris) (Incidentally, this is the episode in which Dr. Smith first utters his classic catchphrase "Oh, the pain.") ~ Hal Erickson, All Movie Guide
