Jojo was a caveman. (Yes, they had names back then). He had a wife and kids. Lots. And he had nits. And lice. And ticks. And fleas. And mites. They drove him nuts.
His wife had all these bugs too. So did the kids.
Jojo was an enterprising caveman. He organised a nit-picking day. The whole cave complex came together for the day, and like all great apes, they went through every square inch of skin and killed the flesh-biting bastards.
Phew! The relief!
To celebrate, Jojo went off and killed a bear. He brought it back, proudly on his shoulders. They cooked the meat and had a feast.
That night, the children slept snuggly under the bear skin. By morning, the bear’s nits had spread.
