Some names have special meanings in popular American expressions. One day, an average Joe was walking down the street. An average Joe is a common person – either male or female. He did not know where he was going. So average Joe asked John Q. Public for directions to the nearest bank. John Q. Public is also a common person – male or female. “Jeez Louise,” said John Q. Public. This is an expression of surprise. “Don’t you know that all banks are closed today? It is Saturday.”

“For Pete’s sake.” said average Joe. This is also an expression used to show a feeling like surprise or disappointment. “I do not believe you,” said he. At that moment, Joe Blow was walking down the street with a woman. Joe Blow is also an expression for a common person. Now this Joe Blow was NOT walking next to a plain Jane. A plain Jane is a woman who is neither ugly nor pretty. The woman with Joe Blow was a real Sheila – a beautiful woman.

Average Joe asked the woman if all banks were closed on Saturday. “No way, Jose,” she answered. This is a way of saying “no.” “No way, Jose. Many banks are open on Saturdays.”

Average Joe did not know either of these two people from Adam. That is, he did not know them at all. But he followed their directions to the nearest bank. [

When he arrived, he walked to the desk and said: “I am here to withdraw some money so I can pay my taxes to Uncle Sam”. This represents the United States government.
