Ha Ha ;)
A stranger walks into a computer store, flags the floor manager and says: "Yes, you have a very fine establishment here."
"The finest" replies the manager. "What can I do for you?"
The stranger continues "I'd like to learn more about PERL."
manager: "Perl sir? Yes, right this way."
stranger: "Not Perl, PERL. The PERL programming language my good man."
manager: "Right sir, perl. We have a very informative display right over here."
stranger: "This is not PERL? I distinctly asked you about PERL. I absolutely must know more about PERL."
manager: "Perl sir?" (getting confused)
stranger: "Yes PERL! Do you know who I am?" (becoming visible agitated)
manager: "Well, no sir. You've just walked into my store." (smug bugger that one)
stranger: "I've heard tell that PERL is the finest programming language in all the land. I simply must learn it."
manager: "Oh, you mean Perl?"
stranger: "Yes PERL."
manager: "Well then, why didn't you say so? Right this way please."
The manager takes the stranger to a shelf of programming books picks out a book called "Learn Ruby in 24 hours" and hands it to the stranger.
manager: "Here you are Sir. The clerk at the front will help you with your purchase."
stranger: "Thank you my good man. You have a very fine establishment here."
The stranger walks out of the store looking quite satisfied.
