The platypus is probably the most iconic aquatic Australian mammal; many advertisements for pools, swimming lessons and fishing gear will use one. It is also used on the Australian 20-cent piece.
Some believe that the platypus proves God has a sense of humor, or He's a total psycho, or He's a stoner, or that evolution is 100% real, because not even God could make that nonsense up. The reasons are myriad. This is an animal that, upon being sent to a British natural history museum to catalog, was believed to be a taxidermist's prank until a live specimen was sent to them. It looks like a beaver crossed with a mole with a duck's bill added for laughs. They belong to a group of mammals known as Monotremes, a group consisting of it and the echidna, which means they lay eggs. Additionally, they're an offshoot of mammals that evolved before teats/nipples evolved, so while they produce milk, they simply... sweat it out for their young to lap up. They also have ten sex chromosomes, where in most mammals there're simply two (X and Y). And their duck-bill? It's actually quite soft, and it acts as an electrical receptor. See, platypus eyes aren't too useful, especially underwater, so they use an electrolocation system in their bills to hunt shrimp and other aquatic invertebrates. (Sharks have a similar sense, in case they weren't threatening enough.) Of course, a real platypus tail looks nothing like a beaver's tail, but that doesn't stop the majority of cartoon depictions from showing one anyway, often complete with thumping behavior. The Platypus also has over-sized webbing on their feet that extends past the claws.
And to top it off, they're venomous. Yup, male platypi have venomous spurs on their feet, and while not lethal to humans, the cocktail of venom will usually incapacitate people, and can cause you to be in excruciating, incapacitating pain that can develop into a persistent ache for weeks or months. So it won't kill you, but you'll wish it did.
So, in short, it's easy to see how humans can become so interested in this goofy-looking creature. Odd appearance, cool features, and the ability to cripple you if you get stupid. What better metaphor for Australia? And it's an Inherently Funny Word. And they swim weirdly. Also, baby playtpi are called "puggles," which is quite possibly the cutest word ever invented, and have been called so since before pugs were crossed with beagles to make the dog breed of the same name (Note: This isn't the official name for a baby platypus, just the most commonly used one. Another just-as-adorable name is "Platypup".).
All good things must come to an end, however. This is slowly becoming a Discredited Trope, because it's gotten so that the platypus has become too popular to be considered "obscure" anymore. When a show is supposed to start including a "weird animal" in its cast, expect it to be a platypus.
Plus, if you want to talk about them in the plural, expect to confound linguists until the end of time. Is it Platypusses? "Platypi?" ''Platypeople''? Whatever. Platypodes, platypi, and platypuses are all acceptable spellings. "Platypus" being a Latinization of the original Greek word, "platypodes" is correctly regular, and "platypi," with a Latin second-declension ending, is commonly considered incorrect in the same way as "octopi" despite the fact that the second-declension inflection for the Greek-derived "-pus" is also perfectly grammatical in Classical Latin, as seen in various attested forms as "Oedipi" ("Oedipus"), "coronopum" ("coronopus"), "polyporum" ("polypus").
- The movie Dogma opens with a disclaimer that religious people who may be offended by the film look at the duck-billed platypus and consider that God must have a sense of humor. This is followed by another disclaimer, apologizing to the "noble" platypus and emphasizing that "it is not our intention to slight these stupid creatures in any way."

- The Last Continent promises that readers may find out why the duck-billed platypus. Not why anything, just... why. As it turns out the wizards, stuck in the past Fourecks decide to help the local god in creating new species, by drawing a duck on a rock, but can't really reach consensus on what a duck looks like. The Platypus results from their squabble, playing to the old joke that the Platypus is a duck designed by a committee.

- In the sequel, More Information Than You Require, the author claims that someone else is now making this movie. Because it's so vague a premise, he is not going to sue, but only asks that he be given a cameo as the guy who gets killed by the duckbilled platypus. IT'S ONLY FAIR.
- There is a child's book featuring a lost platypus with the other animal characters picking up on his individual features and assuring him that he's a duck, a rabbit, a frog, etc. The story ends with him finding his place in life. As a sideshow freak.
- A short story, "The Platypus of Doom," collected in The Platypus of Doom and Other Nihilists, featured the narrator seeking to have a wish granted by the all-powerful Platypus of Doom.

- In Vladimir Vasilyev's Antarctica Online, a team of Russian researchers at an Antarctic base is getting drunk with their Australian colleagues. One of the (drunk) Russians keeps asking an Australian guy about what platypi are like. The guy points out that, like most Australians, he lives in a city, which means he's never seen a platypus outside a zoo. He counters by jokingly asking if the Russian guy has even seen bears prowling the streets of his hometown, as the stereotype goes.

- The plot of the Flash game Cellcraft involves platypi from outer space.

It's other promised features (claws, venomous barbs, being a crime against nature) are technically true, as the platypus does have small claws for burrowing, and the males have small venom barbs on their hind legs, and they're duck-billed mammals which is pretty sinful against nature. Unsurprisingly, he bought the platypus from Akbar and didnt bother to double-check.
- Cheap Caffeine has a running joke based around the religion of Platypism.

- Well, this is Icarus...

- Inverted for anyone who's been the victim of platypi venom, one of the most potent venoms on Earth. While it won't generally kill you, it will make you wish it had as the venom goes to your pain receptors and cranks Up to Eleven. One victim of the venom had been shot in World War II and said without any hesitation that the platypus sting was far more painful. Also, notably, venomosity was actually the ancestral condition for mammals, so in a sense platypi are better because they're the only living mammals with this kind of venom.note
- Platypus babies are named puggles. Puggles is an official word in the English language. That should make you smile in its own right.
- An interesting fact: During World War II, Winston Churchill decided he'd like some brought to the United Kingdom. This required special facilities being fitted out on a ship and navigation halfway round the world during a war. Nevertheless, this was attempted and the ship made it all the way to the mid-Atlantic when it was discovered that the measures taken to protect the animals didn't completely mitigate the effect of anti-submarine depth charges; they died a few days before arriving.
