Because I like it...
from the Land of Og playbook
"Strong Caveman spends most of his day trying to get the loudest "ow" out of others. Though generally not appreciated by everyone, Strong Caveman also makes it a point to pick up everything he encounters. Look! A rock (lift/drop). Look! Another rock (lift/drop). While not the most productive time spent during the day, other cavemen have discovered great uses for this skill.
While watching Strong Caveman continuously pick up a rock and drop it back down in front of a cave entrance, another caveman felt the cave would be a great place to get out of the rain. The other caveman walked over and walked under Strong Caveman when he picked up the rock. He couldn't quite get under it though because Strong Caveman kept dropping it. He then though to say, "Go rock." and pointed to another caveman. He entered the cave - thus the origin of smart caveman.
What about Strong Caveman and the rock? Well, not only was strong caveman feeling pretty cool walking around with the rock over his head, he was getting tired. It seems that holding something heavy over his head for a long time gets pretty tiring, but he had to "Go rock" to the other caveman. Each step was a strain on his bulging biceps. They eventually gave way and Strong Caveman let the rock go with his last ounce of strength. The rock, ever so gracefully, landed right on the foot of the other caveman. The caveman was shocked. His only words, which are unknown to the world, were "Fruck" and "Shlit". Anthropologists believe this might have been the origin of the two most popular words in the English language.
Not knowing what else to do, the other caveman turned and grabbed a large stick right next to him, walked up to Strong Caveman, and banged him over the head - thus the origin of Bangy Caveman."
