A man wanted to prove to a group of alcoholics the effect of alcohol in human body system. He brought two jars; one containing water and the other containing alcohol, along with a very healthy worm. He said to the audience:

"This jar contain water"
He dropped the worm in the jar and said, "Please watch the reaction". The worm swam to the side of the jar and up it floats dangling and swimming.

The man took the worm out of the first jar and put it in the second jar containing alcohol and said to the audience " now watch the reaction" The worm went right down into the water and struggled for survival. There and then every body saw the worm shrinking and dis-integrating, and in one word, died.

The man turned round an asked the audience " what would you all say to this".

After a long silence, someone from the rear stood up and said:

" I can see that if I drink alcohol, there will be no more worms in my body".
