A 4th Grade Class A Teacher Takes 4 Glasses.

In front of her 4th grade class a teacher takes 4 glasses and fills them up with brandy, wine, beer and water.

Then she puts a worm inside each one and let them sit for the night.

The day after she shows to the students each glass and, without any suprise, all worm but the one in the water are stone dead.

“So – she ask the students – what did this experiment teach us?”

From the back of the class the hand of Little Johnny rises up.

“Well, Miss, this experiment taught me that, if I drink brandy, wine or beer, I’ll never get worms!”
