Worm

In an elementary school...

Teacher: "Kids, what we are going to do is doing an experiment. We have a glass of water and a glass of vodka. I bring two worms, and we put the worms into the glasses, one in vodka and one in water."

The teacher put each worm into a glass. A few minutes later, the worm in the glass of vodka was dead, but the worm in the glass of water was alive.

Teacher: "So, kids, what's our conclusion from this experiment?"

Students: "WE HAVE TO DRINK VODKA SO THE WORMS IN OUR BODIES WILL DIE! WE WON'T BE WORMY!"
