Hoping to retrieve Tabitha's toy flying saucer, Aunt Clara accidentally summons a genuine spaceship from the dog star Sirius, bearing two canine-like aliens named Alpha (Hamilton Camp) and Orvis (Steve Franken). The crisis intensifies when a pair of Air Force officers (Larry D. Mann and Eldon Quick) descend upon the Stephens household. Originally telecast April 18, 1968, this was the final Bewitched episode to feature Marion Lorne as Aunt Clara; Lorne died on May 9 of that same year. "Samantha's Secret Saucer" was written by Jerry Mayer and Paul L. Friedman. ~ Hal Erickson, Rovi
