A man walks into a store that specializes in trained monkeys. In amazement, the man walks to a corner and sees a monkey for sale for $5000.
“What does this monkey do?”, asks the man.
The store owner replies, “That’s a laborer monkey, he can set forms, build walls, and shingle roofs.”
“What about this one?”, asks the patron as he motions towards the $20,000 monkey.
“That’s a foreman monkey. He can tell all of your laborer monkeys what to do. Monkeys are a PIA, so you need one that can keep them in line”
“OK, but what does the $50,000 monkey do?”
“He just sits on his ass, drinks beer, and plays computer games. He’s the Project Manager”
