There were 2 cavemen, Ug and Og. Ug was sat in his cave w**king he had just invented it when Og walked in.

"What you doing?" said Og. "W**king" said Ug.

Ug showed Og how to do it and Og left to try it for himself. Later, Ug heard a oud scream from Ogs cave and ran in. Og was sat on the floor with his d**k in one hand and a club in the other. "What happened?" asked a curious Ug. No reply. "What happened Og?" After a minute or two Og replied, "when I tried that thing you taught me, it spat at me so I hit it with my club!"
