1. Can you imagine? When scientists first discovered the platypus, they tried to pull off its "fake" bill. (Platypus: Scientists have no sportsmanship either!)

2. Every time you shuffle the cards, you're potentially making history because there are 52! possible arrangements of a deck of cards. 52! = 52 × 51 × 50 × ... × 2 × 1. Therefore, the current card arrangement after each shuffle may never have existed before. (Turns out I'm making history every time I play Spider Solitaire!)

3. Male penguins will offer female penguins a pebble. If the female accepts, they become mates. (Take this pebble, and you're mine!)

4. Snapping your fingers isn't the sound of rubbing two fingers together, but the sound of your fingers striking your palm. (I couldn't help but snap my fingers in the office.)

5. NASA provides male astronauts with pre-fitted urine bags in small, medium, and large sizes. Everyone chose the large size, no one chose the small or medium, so the bags frequently slipped down. NASA had no choice but to change the sizes to "large," "gigantic," and "humongous." (Give me an "infinity" size!)

6. The human thigh bone is harder than concrete. (If it weren't for my limited pain tolerance, I'd really like to bump into a concrete slab.)

7. Most people will try things that are simple and can satisfy their curiosity, such as the 4th little-known fact.

8. It is said that one in 25 British fathers is raising another man's child. According to a survey by the British newspaper *The Guardian*, between 1950 and 2004, approximately 24,000 of the 600,000 babies born each year in England and Wales were not their fathers' biological children. (I hear raindrops falling on the green grass)

9. The round holes on plastic stools are for easy transport. When a bunch of stools are stacked together, they form a sealed space. Without these holes for ventilation, the stools would be difficult to separate. (I got killed by my classmates countless times when I was a kid because of these holes!)

10. When you're asleep, you can't sense any smells. While sounds can disrupt sleep, smells can't. A Brown University study showed that a sleeping person cannot be awakened by the smell of burning food; they still need other sensory organs to detect and escape. (But why does my roommate always wake up when I make instant noodles?)

11. If the moon is directly overhead, you will lose a little weight. (A true physical weight loss method)

12. In 2011, a Russian suicide bomber received an unexpected text message from her wireless carrier, which triggered her belt bomb and killed her. The message wished her a Happy New Year. (The carrier: We're not taking the blame for this!)

13. To test whether anyone would actually read a software license agreement, a software company once embedded information about a $1,000 bonus in it. Five months later, after selling over 3,000 copies, someone finally called to claim the prize. (To protect my interests as a consumer from unfair terms and conditions, I've decided to carefully read every agreement ever since.)

14. According to statistics, more people are killed by donkeys each year than die in plane crashes (do the deceased all have donkey hoof prints on their heads?).
