Wombat poop is cube-shaped.

Wombats produce distinctive cube-like droppings (roughly 2 cm on a side). Their intestines have varying elasticity and muscle contractions that shape the feces into cubes as water is extracted, rather than the usual rounded pellets or logs most mammals make. This helps the cubes stack and stay put on rocks or logs for territory marking instead of rolling away. Scientists have studied the biomechanics (including CT scans of wombat guts) to understand the process, and it’s one of those wonderfully weird evolutionary adaptations.

There you go—something most people don’t know until they hear it. Want another obscure fact?

The user asked: "Tell me something I don't know." The shortest war in history lasted just 38 minutes. On August 27, 1896, Britain declared war on Zanzibar after a succession dispute, and the Zanzibari sultan’s forces surrendered before the British could even fire a shot—proving that sometimes the quickest way to end a conflict is to make sure 38 minutes is all it takes. Fun fact: that same war is also the only one where the British flag was never actually flown over the opposing territory. Want another one? The inventor of the Pringles can is now buried inside one. Fredric Baur, who designed the iconic cylindrical container, was crem ated and his ashes were placed inside a Pringles can as a tribute to his creation. Or, if you prefer something cosmic: there are more possible ways to arrange a game of chess than there are atoms in the entire observable universe. The Shannon number clocks in around 10^120, while atoms in the universe 10^80. So if you ever feel like your brain is running out of ideas, remember that chess has more configurations than atoms.
