Those Who Don't Know

The world is divided into two groups. There are those who know, and those who don't know. Those who know are no problem.
Those who don't know are also in two groups. One is those who don't know and know they don't know. Well, they can learn!
But then, there are those who don't know, and don't know they don't know. And they become unit managers!

Legendary Explorer's Interview

A young reporter went to a retirement home to interview an aged but legendary explorer. The reporter asked the old man to tell him the most frightening experience he had ever had. The old explorer said, "Once I was hunting Bengal tigers in the jungles of India. I was on a narrow path and my faithful native gun bearer was behind me. Suddenly the largest tiger I have ever seen leaped onto the path in front of us. I turned to get my weapon only to find the native had fled. The tiger leapt toward me with a mighty ROARRRR! I soiled myself." The reporter said, "Under those circumstances anyone would have done the same." The old explorer said, "No, not then - just now when I went 'ROARRRR!'"

Parrot

A man goes into a pet shop to buy a parrot. The shop owner points to three identical looking parrots on a perch and says: "The parrot on the left costs $500 dollars". "Why, does the parrot cost so much?" asks the man. The owner says, "Well  the parrot knows how to use a computer". The man then asks about the next parrot and is told that this one costs $1,000 dollars because it can do everything the first parrot can do plus it knows how to use the UNIX operating system. Naturally, the increasingly startled man asks about the third parrot and is told that it costs $2,000 dollars. Needless to say this begs the question, "What can it do?" To which the owner replies, "To be honest I have never seen it do a thing but the other two call him boss!"
