Ug and Gug were right clever cavemen, who thought they knew it all. They didn't rate Mug very highly, but they put up with him because he was useful to send out to kill a brontisawus for lunch.
One day Ug got an idea. For ages everyone in the world had used felled trees to move heavy loads along. Trouble was it was an ungainly way to move things, and took lots of men and effort to keep moving the trees to be in front of the load.
Ug thought if he could find a way to cut through the trees at the right point in their length he might have something useful. So he made a saw out of bone and teeth, and he got Mug to use it. Ug told Mug that what they were doing would make them both famous.
When Mug has sawn off four round pieces of timber, Ug got Mug to make a platform by sawing trees lengthwise, and then using strips of animal skin to tie the round sections ot the platform. It didn't move! So Ug came up with another idea, and with the addition of a hole in the middle of eash round piece of wood and some wooden poles, (cut by Mug, of course), soon they had a platform with wheels.
Along came Gug. He immediatly saw the potential in the invention. Gug set about thinking of ways to make sure that everyone in the world would know of this clever and useful innovation.
Mug went back to work, leaving Ug thinking how the platform could come in lots of different sizes for different uses, and Gug trying to think of a logo.
Mug cut smaller trees into the right sections, and made a much smaller version of the platform on wheels. He added a 'T' shaped piece of wood to the front, so that when he stood on the platform he would have something to hold onto. Then Mug go onto the platform, and pushed it along with one foot on the ground.
Mug scooted along quite quickly, and this realy impressed the girls. Soon Mug had lots of lady friends, and as was the custom of the time, soon lots of Mug's lots of lady friends had babies. Mug then journeyed across miles of countryside, and everywhere he went he left lots of little mugs behind him.
As the years went by Mug's offspring began to dominate the gene pool.
Ug and Gug never did get very far from where they started, but they had lots more big ideas, some of which worked. Sadly neither Ug nor Gug had any kids, and so with their demise intelligent men died out.
