A man walks into a Silicon Valley pet store looking for a monkey. The storeowner points towards three identical looking monkeys in politically correct, animal-friendly natural mini-habitats.

"The one to the left costs $500," says the storeowner.

"Why so much?" asks the customer. 

"Because it can program in C," answers the storeowner.

The customer inquires about the next monkey and is told that "That one costs $1500, because it knows Visual C++ and Object-Relational technology."

The startled man then asks about the third monkey.

"That one costs $3000," answers the storeowner.

"$3000!" exclaims the man. "What can that one do?"

To which the owner replies, "To be honest, I've never seen it do a single thing, but it calls itself a Consultant."
