What Happens: In order to distract the guards surrounding hostages in Paradise City, Lt Uhura performs an erotic feather-and-fan dance silhouetted by the twin moons of Nimbus III.

Why It's Stupid: Because even goons in intergalactic outlaw towns know that women don’t spontaneously erupt into seductive dance. And if the action scenes the later sequels asked of an increasingly rotund William Shatner were daft, then stripping off the late-50s Nichelle Nichols is equally ill-advised.
