“Excellent!” said Sister Catherine. “And what it is used for?”

“To help you sleep”, replied the student.

“And what is it used for, Johnny?” asked the surprised Sister catherine.

“It is used for diarrhea.”

“And who told you this, Johnny?”

“Nobody, but every evening my mother tells my father,…

‘take a Viagra, and maybe that sh!t will get harder.’”
