Most Useless Inventions by Humans

USB Pet Rock Its funny because you just have have a pet rock on your computer sitting there while you laugh at it but it's so useless and for the fact that is so useless, that's what makes it more funny.The entire point of the original Pet Rock was the instruction book, not the rock itself.

UroClub That part in the commercial where he's using it in the kitchen...ugh, gross! I would kind of feel sorry for someone who had to tell their spouse not to urinate in the kitchen, especially with kids running around. Besides, most houses have a bathroom, so that's just crude and lazy.

Ctrl Alt Delete Wand The Ctrl Alt Delete Wand allows you to press the 3 buttons simultaneously on your keyboard – a task needed to reboot or unfreeze Windows PCs. I guess it's really such an immense effort to use the Ctrl+Alt+Delete shortcut, that we needed a shortcut for it too.

Butterstick The butterstick showed a lot of promise when it was first introduced. It's just like an adhesive stick, except it has butter in place of glue. Unfortunately, the idea never caught on, and the danger that it might be confused with an actual glue stick has pulled the plug on it permanently.

Baby mops This disturbing invention is basically a mob strapped to the belly of your baby. Someone thought it to be a good idea that, while babies crawl, they could also mop the dirt off your floor and save you the trouble. Aside from being completely impractical, baby mops are also unsanitary, as you might imagine.

Shoe umbrellas If you don't want your shoes to lose their shine, this new invention might help. It consists of tiny, cute umbrellas placed on your shoes. Still, aside from looking completely ridiculous, they're also impractical and could end up making it difficult to walk at all.

Solar Powered Cigrattes This is one of the few useless inventions that might have had a future at some point. It uses a magnifying glass to focus sunlight on the tip of your cigarette. It was a good intention that, unfortunately, took an awful long time to light anything up.

Two-person sweatshirt The two-person sweatshirt was marketed as a “sweet shirt” for inseparable spouses or partners who love doing everything together. Now it's easy to see why this invention never really caught on – actually, I have a feeling it might have actually broken off a few relationships in the process.

Cat wigs At last, there's a good remedy for all those cats out there suffering from baldness! While some cat people might consider them cute, cat wigs have no real use or purpose, and the cats themselves want nothing to do with them! "Dare to put that thing on my head again, human slave, and you'll face fatal consequences!"

Subway chin rest Ever wanted to keep yourself from falling asleep while taking the subway to work in the morning? Now you can, with the mobile subway chin rest – a useless invention designed by the Japanese solely to support your chin (while also making you look completely insane).
