Dr Livingstone is walking through the jungle and comes across a clearing with a huge hippopotamus lying stone dead in the middle of it. On top of the hippo is a pygmy. Dr Livingstone approaches him and asks: “Did you kill that?” The pygmy replies: “Howrya. Yes, I did.” Dr Livingstone is surprised by this and continues by asking: “How did you kill it?” “With my club,” replies the pygmy. Dr Livingstone asks: “How big is your club?” “Oh, there's about twenty of us at the moment,” says the pygmy.
