2. "Threshold" - Star Trek: Voyager (season 2, episode 15)

"Threshold" episode, also known as the one where Captain Janeway and Lieutenant Paris turn into lizards, is often cited as a high watermark in the "what were they thinking?" department of the Star Trek universe. This episode, which boldly goes where no evolutionary theory has gone before, tackles the ambitious concept of breaking the Warp 10 barrier, a feat similar to breaking the sound barrier but with more technobabble and less exciting.

The episode starts with Paris achieving this miraculous feat, only to discover that traveling at infinite velocity comes with some unexpected side effects, like evolving into a new life form faster than a Pokémon on steroids.

The episode's descent into the bizarre doesn't stop there. Paris, now mutating, kidnaps Captain Janeway and takes her on a Warp 10 joyride. When Voyager finds them, they've evolved into salamander-like creatures, complete with a brood of offspring (because why not add a dash of amphibian romance to the mix, right?). The scientific explanations offered in the episode stretch credibility thinner than me on a regular weekday.

Fans and critics alike have often pointed out the logical inconsistencies and scientific inaccuracies in "Threshold." It's not just that the crew reverts to their human forms with no lasting effects (because apparently, you can just hit the undo button on rapid, forced evolution), but the sheer audacity of the plot turns "Threshold" into a campy, almost B-movie-esque plunge into the sci-fi absurd. In the universe of Star Trek's rich storytelling, "Threshold" stands out like a sore thumb, offering a tale so bizarre that it's become a legend in its own right.
