The next day he went to the pet shop and saw three identical green parakeets in a cage. He asked the clerk, "How much for the parakeet on the right?"

The owner said it was $250.

"$250", the man said. "Well what does he do?"

"He knows how to use all of the functions of Microsoft Office 97", responds the clerk. "He can do all of your spreadsheets and type all of your letters."

The man then asks what the second parakeet costs.

The clerk replies, "$500, but he not only knows Office 97 but is an expert computer programmer."

Finally, the man asks about the last parakeet.

The clerk replies, "$1000."

Curious as to how a bird can cost $1000, the man asks what this bird's specialty is.

The clerk replies, "Well, to be honest I haven't seen him do anything. But the other two call him boss."
