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 in the world does that parrot cost so much?” asks the man.

The shop owner says, “Well, she knows how to use a computer. Types 100 words a minute, too.”

The man then asks about the next parrot and is told that one costs $1,000… because it can do everything the other parrot can do, plus it can do accounting.

Then the man asked about the third parrot, and is told that it costs $2,000. He has to know why, so he asks, “What amazing things can it do, for such a steep price?”

The shop owner replied, “To be honest, I have never seen it do a thing, but the other two call him Boss.”
