- The Cage & any episode with green-skinned Orion women
The one other TOS episode with a green-skinned Orion woman was the third-season ep "Whom Gods Destroy." That was the one where the inmates have taken over an interstellar lunatic asylum, with the megalomaniacal Garth (Steve Ihnat) as their leader and Yvonne "Batgirl" Craig as Marta, his equally batty girlfriend. Damn, she looked hot in that episode. Green women rock!

- the one with Michael Dunn in a faux-Roman setting . . .
"Plato's Stepchildren," and it was faux-Greek, actually.

The one with all the babes on a planet and Ted Cassidy is an alien
Ted Cassidy played an android in the first-season ep "What Are Little Girls Made Of?" It had just one babe, though -- the delectable Sherry Jackson in one of William Theiss' famously sexy costumes.

Cassidy also provided the booming voice of the false Balok in "The Corbomite Maneuver."
