Wolf in the Fold (TOS)

Star Trek: The Original Series, Series 2, Episode 14. First broadcast on Friday 22 December 1967. Stardate: 3614.9.

When simple, mild-mannered lackwit Montgomery Scott (James Doohan) stabs three women to death in the space of a couple of hours, the crew of the Enterprise become suspicious enough to start an investigation, which mostly consists of getting Majel Barrett to read them a bunch of Wikipedia articles. But just as we’re all about to nod off, someone claims responsibility for the murders — beloved childhood plaything Piglet (John Fielder), who immediately inputs himself into the ship’s computer and attempts to generate terror by making a series of increasingly unimaginative violent threats. Understandably, the crew respond to all this by taking a bunch of drugs and waiting for the closing credits to kick in. Which is how we recommend that you respond to this episode as well.
