This guy walks into a bar.  He walks up to the bartender and asks for a rum
and coke.  The bartender puts an apple on the table.  The guy looks at it
and repeats, "I said I want a rum and coke."

The bartender says just try the apple.

So the guy bites into the apple and replies, "Wow! This tastes like rum."
The bartender tells him to turn it around.  He bites in again and replies,
"Wow, it tastes like coke."

A minute later another guy walks into the bar and asks the bartender for a
gin and tonic.  The bartender puts an apple on the table.  This guy, just as
confused as the first explains he wants a gin and tonic.  The guy next to
him urges him to try it.  So the guy bites into it.  "Wow! It tastes like
gin."  The guy tells him to turn it around.  He bites in it again.  "Wow!
It tastes like tonic."

Later that night another guy walks in a joins the two guys at the bar.  The
guys are so excited about these apples that they tell this guy that the
bartender has an apple for which ever taste you want.  So the guy asks for
an apple that tastes like pussy.

The bartender puts the apple on the table.  The guy bites into it and says,
"This tastes like SHIT!!!"

The bartender replies, "Turn it around!"
