Forgive me dear readers for straying a little bit off topic here, but this stuff is too good not to share. Chindogu are inventions that are considered "unuseless" because as they solve everyday dilemmas, using them causes so many additional problems that they aren't worth trying at all.
Check out the Fish Face Cover, which "helps get the fish cut up with minimum emotional trauma," or The Earring Safety Net. Which of these things do you find most useful? Extra credit: take some time over the weekend to come up with chindogu of your own.
