The storekeeper nodded, went to the side of the store, and took out a monkey. He put a collar and leash on the animal and handed it to the engineer, saying, "That'll be $2000." The man paid and left with the monkey."
The surprised tourist went to the storekeeper and said, "That was a very expensive monkey. Most monkeys are only a few hundred dollars. Why did that one cost so much?" The storekeeper answered, "Ah, that's a rig monkey. He can rig up, plan rig moves, rewind motors, tail pipe, paint, pull maintenance, all with no back talk or complaints. It's well worth the money."
The tourist then spotted a monkey in another cage. "That one's even more expensive!! $10,000 !! What does it do??" he asked. "Oh, that one" replied the storekeeper. " That's a Rig Manager monkey. It can instruct at levels of maintenance, run the safety program, deal with clients, and even do some paper work. A very useful monkey indeed."
The tourist looked around a little longer and found a third monkey in a cage. The price tag was $50,000. The shocked tourist exclaimed, "This one costs more than all the others put together !!. What in the world can it do??". "Actually," said the shopkeeper, "I've never really seen him do anything but drink beer and whiskey and make a lot of noise, but his papers say he's a Company Man."
