Farscape/Fridge

Fridge Brilliance

 * In Farscape, particularly the quote at the top of that page, John Crichton rattles off a list of Sci-Fi heroes, and then says that he's not like any of them, instead likening himself to Dorothy Gale, from The Wizard of Oz. At face value, this makes sense, as Dorothy is an ordinary person in a crazy world like he is, but that applies to some of the other Sci-Fi heroes he lists as well. I didn't think much of it at first, but recently I realized how alike they really are: Both are regular people, doing their jobs, living in a backwater nowhere place (Kansas, Earth) who get sucked up by a swirling vortex (for Dorothy, a Tornado, and for John, a Wormhole) and deposited in a faraway place (Oz, the other side of the Galaxy). Their first act in the new land is to accidentally kill a relative of someone very important and apparently, very evil (Wicked Witch of the East, Crais' brother) and immediately make an enemy of the survivor. They both survive in this strange land by meeting up with the locals, including a deposed former ruler (Scarecrow, Rygel) and the big strong guy. Eventually, after searching for a way home, they each decide they much prefer the strange new world and choose to stay. - Terral
 * Dorothy chose to stay in Oz?
 * The Wonderful Wizard of Oz had thirteen sequels. Dorothy emigrated permanently somewhere around book five.
 * In "DNA Mad Scientist," Namtar offers D'Argo, Zhann and Rygel the way back home in exchange for Pilot's DNA, so they cut off his arm. Crichton is naturally appalled, but surprisingly so is Aeryn - who reasons that Pilot is a defenseless creature. Flashbacks from "The Way We Weren't,", really explain why she is so appalled.
 * The episode "The Ugly Truth" plays heavily with the concept of perception, and how different people can see the same events different ways. Throughout the episode Crichton calls the Plokavians, the aliens interrogating them over a crime, "Plokavoids" (a Running Gag in the series is that Crichton frequently experiences difficulties pronouncing the names of various aliens and their species). When it comes time for the Plokavians to hear Chrichton's testimony, the flashback shows everyone on the crew calling them Plokavoids because their dialog is actually Crichton's retelling of the events.

Fridge Horror

 * Farscape had a character experience this in-canon about their experiences. At the end of the episode "The Locket", Zhaan is congratulating herself on helping the crew escape from a time anomaly, which led to time being rewound so that they never actually entered it. Then she realises that this might have led to the children and grandchildren that Aeryn had during two hundred years of subjective time trapped on a planet within the anomaly being erased from history.
