Oogamagook on Innovation

Oogamagook, the Neanderthal had, hanging on his wall, a great big square thing made of solid stone, and in the middle of it was a hole. One day, he had to go from his cave in Hastings to his uncle's cave in Bath. That's quite a large distance for the modern troglodyte to take on foot, and he was dreading the trip, not to mention the fact that his uncle was an utter bore. As he was packing, he found himself lost in thought (a strange place for him), staring at the great big square thing. He suddenly lept up, exclaiming, "Eureka! All I have to do is round off those corners and buy a set of tires, and, hey, that's a wheel!" Oogamagook was a happy barbarian that day, as, not only did he not have to make the entire trip on foot, he had missed his appointment with his uncle because it's hard work to carve a wheel out of solid stone.
