... reminded me alot of Ms. Lincoln from the TOS Gary 7 episode. I've wondered if the one wasn't inspired by the other. Teri Garr also went onto great stardom after her turn as a loopy chick in STAR TREK, as evidenced by her role in the epic Science Fiction Classic: Close Encounters of the Third Kind.
Actually, she played two similar roles around that time: both were the put-upon wife whose husband
had gone nuts (Richard Dreyfuss kept seeing UFOs and building Devil's Tower in his living room and John Denver kept having conversations with God).
