A tourist walked into a pet shop and was looking at the animals on display. While he was there, a Chief Petty Officer walked in and said to the shopkeeper, "I'll have an Seaman monkey please." The shopkeeper nodded, went over to a cage at the side of the shop and took out a monkey. He fit a collar and leash, handed it to the Customer,saying "That'll be $1000." The Chief 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 dollars. Why did it cost so much?" The shopkeeper answered, "Ah, that monkey can clean heads and passageways, perform routine maintenance on ship or hangar fittings, troubleshoot and repair complex avionics systems with no mistakes,well worth the money."Ah, Chief humor.
The tourist looked at the monkey in another cage. "That one's even more expensive! $10,000! What does it do?" "Oh, that one's a Petty Officer monkey; it can instruct GMT, CSTT, PRT, DC, 3M, PQS qualify the Seaman monkey and even do some paperwork. 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 Officer."
