In the last year, we've seen the worldwide popularity of selfie sticks skyrocket. Selfie sticks have become so popular that several celebrities are even starting to use the phone-holding-arms.

But while the popularity of selfie sticks might be new, the item itself has actually been around for years. In 2000, author Kenji Kawakami wrote a book called 101 Unuseless Japanese Inventions featuring — you might have guessed it — selfie sticks.

The book is all about what is known as chindōgu in Japan. Chindōgu is another term for an odd everyday object, or, as Kenji Kawakami calls it, a "weird tool." Some other examples of these offbeat inventions are a treadmill bike, duster slippers for cats, and a face guard to protect your hair from getting in your noodles. 

People might have thought the idea of a stick that will help you take photos of yourself was funny in 2000, but it looks like Kenji Kawakami is having the last laugh.
