Trekathalon TOS: 1-9 Dagger of the Mind

"Blue paper bits down three, yellow up one..."

Man, if Kirk isn't getting his shirt ripped off, he's being strapped to some mad-scientist's diabolical thingy.  Today's diabolical thingy is a mind-wiper designer to pacify criminals.

Guest stars include the lovely Marianna Hill (who may have been in Cheif Zabu, which may or may not actually exist, but she was neither Zack Norman, or Sammy, so who knows), as ship's psychiatrist and woman-of-action; and Morgan Woodward, who is seriously uncomfortable to watch, as he conveys the effects of the mind-wiper by gagging and choking painfully.

Star Trek sure started out heavy with the mad scientist, and intruders running amok on the ship.
