Spooge's Spit Up - CAD Monkeys

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 CAD 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, handed it to the customer, saying, 'That'll be £5000.'

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. Most of them are only few hundred dollars. Why did that one cost so much?'

The Shopkeeper answered, 'Ah, that monkey can draw in AutoCAD - very fast, clear layouts, no mistakes, well worth the money.'

The tourist looked at a monkey in another cage. 'That one's even more expensive! £10,000! What does it do?'

'Oh, that one's a Design monkey; it can design systems, layout projects, mark-up drawings, write specifications, some even calculate. 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 Engineer.'
