A man goes inside a pet shop and starts to move around the cages to look at the pets.
He sees a monkey with a price tag of $5,000. This makes him curious, as most other monkeys are $500 at most. He then goes to the merchant to ask for details.
"Hey mister, the monkey…what does it know to worth that much money?"
"That's our computer monkey. It knows Windows 7 and windows 10, and also knows Word, C++, .net,
app programming, and last but not least, it knows how to fix computers if yours breaks."
"Wow!" Declared his customer. "That's a good monkey, well worth the money."
He goes and finds another monkey with a price of $10,000 and again he will ask the merchant.
"What does this monkey know?"
"That's a highly specialized monkey. It knows 5 languages and can translate fluently between them."
"That's amazing!" Says the man excitedly. "That's WELL worth the money!"
"Yea, but if you buy one you have to buy all three. They work together."
The man follows the seller's pointing finger to yet a third monkey, just sitting there with a price tag of $20,000.
"Gosh, what does THIS monkey to justify that ridiculous amount of money?"
"To be honest, I've never seen him doing anything, but the other two call him Project Manager."
