A few years ago there was a company who put out sure-fire diet pills, guaranteed to lose weight in no time. People began to take these pills, and in no time the people were losing weight. After a few weeks these people began to lose too much weight. So the government investigated. They opened the pills and found the head of a tapeworm.
Tapeworms are hard to get rid of.
They had the person starve himself for days. Then they set a bowl of hot milk in front of the person. He had to keep his mouth open. After a while the tapeworm began to come up his throat 'cause he smelled the milk. They kept moving the bowl further away until the tapeworm was completely out.
