What idiot Invented the Wheel?

Actually, the inventors of the wheel were no idiots. The first known wheels were most likely used in Ancient Mesopotamia around 3,500 BC. The Mesopotamians used the wheel for carrying large items on what is known today as a cart or carriage. The invention of the wheel paved the way for chariots, 'advanced' carriages, coaches/wagons, hauling devices, the wheel and axle, as well as the automobile.

On the lighter side

Gronk did it. He got seriously annoyed when Sheila his mate looked around the Hungry Man establishment and decided that it needed a serious remodeling. Sheila, like most women, had an aversion to casual nonsense such as trading items cluttering up the eating space by the fire. She demanded that he remove the valuables to another location.

Gronk was in a quandary. Now, not only did he have to leave his beloved y'ron rocks and barbeque recipes, he must lug all that stuff from the eating establishment to an unspecified location. Upon inquiring, he learned that Sheila expected him to not only move the assortment from the restaurant, but to provide a new secure place to put them. This was surely beyond one man's capabilities!

Still grumbling, Gronk sought his sworn companion Ogg. Ogg's trading emporium was similarly encumbered, but Rhonda had not made such a demand. Having had experience with cohabitation arrangements throughout the tribe, Ogg knew that it was only a matter of time before he would be faced with the same demand.

Immediately it would seem that the problem was to remove the trade goods from both establishments. The intrepid pair looked over the piles of goods and came to the conclusion that they indeed needed somewhere else to stash their respective hoards, but where? Their living quarters were out of the question as this would precipitate another war with their mates. The two considered destroying some of the goods, but this would be counterproductive since they had traded hard earned services for them.

After surveying the massive problem, they wandered around the village and discussed the problem.
Not being a big guy Ogg decided to sit on a particularly large rock among a pile of rocks to think. Gronk, being a doer rather than a deep thinker, began to pick up the smaller rocks around Ogg and roll them further down the trail. Ogg was not paying too much attention but he did when the rock he was sitting on began to roll. With nowhere to go, Ogg had to be nimble and scramble backwards as the rock rolled forward. It was not long before he was several yards down the trail. Gronk stood watching in amazement. Ogg was small but he was compact and was not easy to move. The rock seemed to have no problem doing so. Both came to the same conclusion. Rock and roll, could this be the answer?

He had to come up with something. So he invented Pi.
Now that has been a problem for children ever since, thanks to their friend Trig.
