There is a guy who visits the mining camps in Western Australia preaching the evils of drink. In his presentation he has a glass of water, a glass of milk and a glass of whisky. He then gets a live worm and drops it in the glass of water. He pull the worm out and it is alive wriggling around. He says this shows you water is good for you. He then drops the worm in the glass of milk. He pulls the worm out and it is alive wriggling around. He says this shows you milk is good for you. He then drops the worm in the glass of whisky. He pulls the worm out and it is stiff as a board stone dead. He says to his audience "What does this show you?" A bloke at the back of the hall yells out "It shows you if you drink whisky you won't get worms!"
