A tourist walks into a pet shop in Silicon Valley, and is browsing
         round the cages on display. While he's there, another customer walks
         in and says to the shopkeeper, "I'll have a C monkey, please".
         The shopkeeper nods, goes over to a cage at the side of the shop and
         takes out a monkey. He fits a collar and leash and hands it to the
         customer, saying, "That'll be $5000".
         The customer pays and walks out with his monkey.
    
         Startled, the tourist goes over to the shopkeeper. "That was a very
         expensive monkey - most of them are only a few hundred dollars. Why
         did it cost so much?"
         "Ah, that monkey can program in C - very fast, tight code, no bugs,
         well worth the money".
    
         The tourist looks at the monkeys in that cage. "That one's even more
         expensive - $10,000 dollars! What does it do?".
         "Oh, that one's a C++ monkey; it can manage object oriented
         programming, Visual C++, even some Java, all the really useful stuff".
    
         The tourist looks round for a little longer and sees a third monkey
         In a cage on its own. The price tag round its neck says $50,000. He
         gasps to the shopkeeper, That one costs more than all the others put
         together! What on earth does it do?"
    
          "Well, I don't know if it does anything, but it says it's a
          contractor."
