A man wanted to buy his son a parrot as a birthday present.
The next day he went to the pet shop and saw
three identical parrots in a cage.
He asked the clerk, "how much for the parrot on the right?
The owner said it was Rs. 2500.
"Rs. 2500.", the man said. "Well what does he do?
"He knows how to use all of the functions of Microsoft Office 2000, responds the clerk.
"He can do all of your spreadsheets and type all of your letters."
The man then asked what the second parrot cost.
The clerk replied, Rs. 5000, but he not only knows Office 2000,
but is an expert computer programmer.
