Learning Medicines

At school Johnny's class is learning about medicines.
Catherine, the teacher, asks the students what kind of medicines they know and what they are used for.

The first student said: "Paracetamol?"
"Very good! And what is it used for?"
"It is used for a headache."

The second student said, "Eno"
"Excellent!' said Catherine. And what it is used for?"
"To help indigestion", replied the student.

Now it is Johnny's turn and he said, "Viagra"
And what is it used for, Johnny?" asked the surprised Catherine.
"It is used for diarrhea."

"And who told you this, Johnny?"
"Nobody, but most evenings my mother tells my father ..."
"Take a Viagra, and maybe that shit will get harder.''

Catherine fainted. Class Dismissed.

Just Kidding!
