"Do Not Fold, Spindle or Mutilate" is a fun made for TV movie from 1971. I am pretty sure the success of this film led to a similar short-lived TV series, "The Snoop Sister"--with two of the same four stars who played the leads in this movie.
When the film begins, four cute old ladies meet for lunch (Helen Hayes, Mildred Natwick, Myrna Loy and Sylvia Sidney). Over lunch, one of them has a hair-brained idea....which shows that these women are really bored and have way too much time on their hands! For kicks, they'll create a fake persona and enter her in a computer dating service-- just to see what happens next. Unfortunately, one of the guys turns out to be total psycho (Vince Edwards)...one that is very scary and resourceful. Little did they know that the fake meeting they set up turns out to end in murder, as the crazed man thinks another woman is his computer date...and when she is confused and tells him to leave, he kills her! Now, he could come looking for the old ladies...or, these spunky old ladies COULD come looking for him! Either way, bad things could easily happen to them!
The reason this ridiculous plot works is that these old ladies are so gosh-darn cute. Additionally, the big confrontation scene with the murderer turns out to be very funny...something I didn't expect. Well made and fun...and one of the more enjoyable "ABC Movie of the Week" installments.
