Helen is playing fetch in the yard with the dogs, and Martha notes that she hasn't seen T.D. or Truman all day. Helen explains that they're still working on T.D.'s version of a Greek myth. Meanwhile, the boys are having trouble finding which myth to rewrite, since T.D. can't find one with a "fun" plot. He asks if there are any with airplanes, and Truman responds in the negative (since planes didn't exist back then), but suggests the myth of Icarus, since while Icarus didn't have an airplane, he flew. T.D. asks for the plot, so Truman explains.
T.D. complains about the Downer Ending, so Truman suggests rewriting it so Icarus survives, but T.D. thinks that's "not much of a story". Truman then suggests the myth of Echo, which he explains. T.D. wonders if he could rewrite the story so that she's only punished to echo people for twenty-two minutes, not forever, but Truman thinks that's not good enough. Truman suggests "King Midas" or "Medusa", but T.D. thinks the gold and stone transformations in the stories are too permanent, so Truman angrily leaves, feeling that T.D. is too picky. However, when he turns on the TV and gets an all-day comedy marathon, he gets inspired.
Meanwhile, Truman is showing an adaptation of a Greek myth he came up with himself to Helen and Carolina. He plays Paethon, Jake plays Helios, and Martha and Skits pull the chariot, which is made from a cardboard box. Martha starts to tell the story, but Truman shushes her. He's about to start his play, when T.D. shows up with his story.
It starts with King Midas, then turns to Medusa, who get married due to bonding over turning people into solid substances. He then shows them getting up to sitcom couple antics, with a laugh track he recorded himself. His friends are bemused by this, but he goes on, showing Midas going to a palace to watch a show and Medusa sneaking in and turning everyone there to stone. Most of T.D.'s human friends are still bemused, but the dogs and Jake like it.
This episode provides examples of
- Adaptational Relationship Overhaul: In T.D.'s story, King Midas and Medusa get married.
- Baby See, Baby Do: When Truman shushes Martha for spoiling the story, Jake copies Truman's shushing sounds.
- But You Were There, and You, and You: Whenever a myth is told, the characters in the story are represented by the main characters (Martha as Echo and Medusa, T.D. as Icarus, Truman as Daedalus and Midas, Helen as Hera and a random woman, and Carolina, Danny, and Mariella as random Greeks.)
- Call-Back: The episode focuses on T.D. and Truman trying to rewrite a Greek myth, which they swore to do in the previous episode "Myth Me?".
- Damned by Faint Praise: After T.D.'s myth adaptation fails to impress everyone except Martha, Skits, and Jake, Truman says it's a story fit for dogs and babies.
- Dawson Casting: In-Universe — Truman (a nine-year-old) plays Paethon (a grown man), while Jake (a baby) plays Helios (Paethon's father)
- Downer Ending: Conversed when T.D. hears that the Icarus myth ends with him drowning in the ocean and says, "Isn't there one myth with a happy ending?!".
- "Eureka!" Moment: T.D. is inspired to write I Love Medusy after seeing a comedy marathon on TV.
- Fun with Homophones: In T.D.'s I Love Medusy story, Medusa says, "This is ancient Greece, and speaking of ancient grease, what's that stain on your toga?".
- Laugh Track: When T.D.'s story I Love Medusy is shown, he plays recorded laughter to punctuate every joke.
- Loophole Abuse: Apparently, Martha once stole Mariella's lunch by knocking it on the floor, reasoning that anything that falls on the floor belongs to dogs.
- Manchild: Or rather womanchild — T.D.'s portrayal of Medusa whines, "I wanna go to the palace!", then later shouts, "Whaaa!" when she's caught having turned the people there into stone.
- Mood Whiplash: The explanation of the Echo myth starts with a silly parody of the theme tune — and then it abruptly switches to Hera punishing Echo by making her unable to speak for herself, just because she called her Juno.
- One-Gender Race: Conversed when Truman observes that nymphs are "always ladies in the pictures".
- Opening Shout-Out: When Truman's explaining the story of Echo, she's shown as Martha, doing similar things to what Martha does in the theme tune — saying, "How now, brown cow" to a herd of cows, asking a Daniel-esque man what a caboose is and a Mariella-esque woman (who's making alphabet soup), when they're eating again, then saying, "Hey, Juno, whaddaya know?" to Hera (who's painting and looks like Helen). Hera then says, "My name is not Juno!".
- Pun-Based Title: The name is a pun on "mistake".
- Screw This, I'm Outta Here: Truman leaves in a huff after T.D. turns down four myths to revise.
- Shout-Out: T.D.'s story is called I Love Medusy, a pun on I Love Lucy.
