A business man is called into his boss' office and told that there's a
deal in Japan that he needs to close.  The boss cautions his employee
that "if you loose the deal, you loose your job."  So the business man
begins to read up on Japanese culture so not to offend anyone.  

He arrives at the airport to be met by a Japanese entourage.  When in
the limo his escort notices his stress and says "relax, tomorrow we'll
play a game of golf and if the game goes well the deal is done."  The
business man becomes even more agitated and nervous.  So the escort
recommends a girl he knows to help calm the business man's stress. The
business man wanting to save face accepts the gesture.

So that night a prostitute knocks on his hotel door.  They start to
kiss and fondle each other.  He puts it in and she says "ichewa" The
business man correlates "ichewa" to an American word of pleasure like
"yummm huh."  The faster he pumps the louder she screams "ichewa"
until they're finished.  The business man thinks "boy, she must've
really enjoyed it."

The next day he's much more relaxed and his golf game is on, so the
business deal is on.  He has to hit a hole-in-one inorder to top off
his game and impress the Japanese businessmen.  Sure enough he hits a
hole-in-one.  He throws his hands in the air and screams "ichewa!"
One of the Japanese business men looks at him puzzled and says "what
do you mean, wrong hole?"
