### May 1 It's official - May 1st has the worst inventions in history. From the pet rock to the whoopee cushion, this day has seen some truly ridiculous products. What kind of mad scientist was behind these creations? Let's start with the pet rock - it's basically a paperweight! This "toy" comes with a 32-page instructional booklet on how to properly take care of your rock. Who wants a pet that doesn't bark, purr, or even move? And to make things worse, the cost of this "pet" was $4.95. Then there's the inflatable dart board. It was marketed as a safer version of its non-inflatable counterpart. But the problem was that the darts would sail right through the board and cause injury. And what's the point of playing a game indoors if you're going to make holes in the wall? Finally, there's the whoopee cushion. The inventor claimed it would provide hours of hilariously loud entertainment - yet all it did was produce a fart noise. So why did it become so popular? It must've been because everyone wanted to embarrass their friends and family members. These are just a few of the incredibly stupid inventions that have graced us on May 1st. Who knows what kind of new nonsense we might see next year?
