Once again, Kirk rounds up incorrigible miscreant Harcourt Fenton Mudd, this time trying to sell a love potion to miners. Once incarcerated aboard the Enterprise, Mudd induces the lovelorn Nurse Chapel into trying it out on Mr. Spock, thereby creating an avenue of escape. Later thinking she's been duped with a worthless product, Christine confronts Harcourt and winds up his hostage in a bid for freedom. The potion, however, does work and, sucked into the air ducts, affects the entire crew. On Mudd's trail, Kirk beams down with the heavily affected Mr. Spock to an apparently lifeless M class planet, where all four find themselves facing behemoths of living rock. Written by statmanjeff

Worth seeing just for the brief Spock-Kirk gay scene...
9 April 2015 | by MartinHaferSee all my reviews

'That's an outstandingly stupid idea'--Spock in response to one of Kirk's ideas.

This episode features Harry Mudd--the third time he's appeared in any Trek series. And, fortunately, Roger Carmel provides the voice for this lovable rogue.

When the show begins, the landing party from Enterprise finds Harry Mudd on yet another planet trying to swindle some idiots. But, when Kirk informs them that he's actually selling them crap, the crowd turns on him and Mudd agrees to go aboard Enterprise as a prisoner. But he is a schemer and soon has another plot to hatch--and it involves giving Nurse Chapel a love potion so she can win her Spocky-poo.

This is a mildly amusing episode. Like the rest, the animation is pure crap--with a super-low cel count (making the characters rather robotic when they move) and very poor drawings. But it IS worth seeing for two reasons--Harry Mudd AND you get a very brief but wonderful scene where Kirk and Spock are getting REALLY chummy because of the love potion run amok! Yes, you see gay Kirk and gay Spock--though unfortunately the drug wears off before they can do the deed. Weird but fun.
