Kal-tar sat next to zug-zug by the fire, when one of them sighs loudly and sits up with a start.
"What's wrong??" asked Zug-zug.
Kal-tar threw his hands up in the air and exclaimed in frustration "I'm tired of shooting flint arrows! they're too mainstream, and the ostriches always get to you before you fire off a second shot!"
"Well, what do you suggest, Kal-tar? Arrows are all we've got." Said Zug-zug.
his friend smiled and shook his head, "You're wrong Zug-zug. We have stone swords."
"Swords?"
"That's right. Stone Swords."
It was from that day forward, that Kal-Tar and zug-zug evolved from mediocre hunters, to slightly less mediocre hunters, who killed shit in style.
