This one could be adapted to suit your requirements:

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 Claims monkey please."

The shopkeeper nodded, went over to the cage at the side of the shop and
took out a monkey. He fitted a collar and lead, handed it to the customer,
saying, "That´ll 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.
Most of them are only a few hundred pounds. Why did it cost so much?"

The shopkeeper answered, "Ah, that monkey can settle claims very fast,
clear records, no mistakes, well worth the money".

The tourist looked at the monkey in another cage.
"That one´s even more expensive. £10,000 - what does it do?"
"Oh, that´s one´s a Wordings monkey; it can design contracts, check
clauses, proof-read very long documents, write wordings, even some law.
All the really useful stuff," said the shopkeeper.

The tourist looked around and saw another monkey - price £15,000. "That´s
an underwriter monkey the owner said. He assesses the risk and calculates
the premium, a very important job.

The tourist looked around for a little longer and saw a fourth monkey in a
cage of it´s own (pissed out of it´s head). The price tag around its neck
read £50,000. He gasped to the shopkeeper,"That one costs more than all
the others all put together! What on earth does it do?"

The shopkeeper shook his head and replied.
"Well, I haven´t actually seen it do anything yet but it says it´s a
broker."
