During a good manners and etiquette class, the teacher says
to her students, "If you were courting a well educated young
girl from a prominent family, and during a dinner for two
you needed to go to the toilet, what would you say to her?"
Mike replies, "Wait a minute, I'm going to take a piss."
The teacher says, "That would be very rude and improper on
your part."
Johnny replied, "Sorry, but I need to go to the toilet. I'll
be back in a minute."
The teacher says, "That's much better but to mention the word
'toilet' during a meal, is unpleasant."
So Charlie says, "My dear, please excuse me for a moment. I
have to go shake hands with a personal friend whom I hope to
be able to introduce you to after dinner."
