Once upon a time there was a man who won a prize at a fair. The prize was a simple certificate on which was written: Congratulations! You have won a Chronic Les.
"A Chronic Les?" the man exclaimed, baffled. "What on earth is a Chronic Les?"
"Ahaaaa!" the prize giver said, rubbing his hands with glee. "It's the shortened form of the name of your prize. The great thing about this prize is that you get to choose one out of three things that Chronic Les could stand for!"
"What are those?" the man asked.
"Chronic Lesbian, Chronic Lesson and Chronic Lesion."
Which one did the man choose (if any) and why?
