"Monkey Business" joke

A tourist walked into a pet shop and was looking at the animals on display.
While he was there, another customer walked in and said to the shopkeeper, "I'll
have a C monkey please."
The shopkeeper nodded, went over to a cage at the side of the shop, and took out
a monkey. He fitted a collar and leash and handed it to the customer, saying,
"That will be $5,000".
The customer paid and walked out with his monkey.
Startled, the tourist went over to the shopkeeper and said, "That was a very
expensive monkey. Why did it cost so much?!"
The shopkeeper answered, "Ah, that monkey can program in C - very fast, tight
code, no bugs, well worth it!"
The tourist looked at the monkey in another cage. "That one's even more
expensive, $10,000! 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," said the shopkeeper.
The tourist looked around for a little longer and saw a third monkey in a cage
of its own. The price tag around its neck read $50,000.
He gasped to the shopkeeper, "That one costs more than all the others put
together! What on earth does it do?"
The shopkeeper replied, "Well, I haven't actually seen it do anything, but it
says it's an SAP consultant."
