Once again, Gladys Kravitz catches Samantha in the act of witchcraft, and once again is unable to convince her husband Abner of the fact. This time, Gladys looks on in fascinated horror as Sam "twitches" open her garage door -- a neat trick, considering that the door isn't automated. To cover Sam's tracks, the Stephenses immediately install a remote-control opener, only to be plagued by a series of malfunctions caused by passing jets (for which, of course, Darrin holds Sam responsible). Its title a play on a once-popular song, "Open the Door, Witchcraft" was written by Ruth Brooks Flippen, and originally aired on April 8, 1965. ~ Hal Erickson, Rovi
