A man had been feeling unwell for about 3 weeks and went to see his doctor.
The doctor told him, "I don't know what you've got but it could be serious so I'm sending you to the Rare Disease Specialist."
The man went to the specialist who told the man, "You have a rare illness that occurs only once every ten years or so. The only cure is made in Australia in a little town called Mercey, about 400 miles from Sydney. You better get there fast; you have only one week to live."
The man took the first flight he could to Sydney, rented a car and drove to Mercey, Australia. When he got there, he found it was a town with a population of one. The man walked up to the one house in the village and an old doctor answered.
"You have to help me!" said the man, "I'm dying of this rare illness and I have only 4 days to live."
The old man invited him in and said, "I must give you my special Koala Bear Tea. It is the only thing that will cure you."
The old man went out to get the supplies. One koala, a few birds, platapus placentas and such. The doctor boiled them together and gave them to the man with bones and feathers and dirt swirling throughout. The young man looked at it disgustingly and asked if it could be strained.
The old doctor looked horrified and said, "Oh No. The Koala Tea of Mercey is not strained."
