Etiquette Class

During a good manners and etiquette class, the teacher says to her
students:

"If you were dating 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 : "Hang on a minute, I'm going to take a piss."

The teacher says : "That would be very rude and improper on your part."

Charlie says: "I'd say, I'm sorry, 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."

And Billy 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
to you after dinner. "

The teacher passed out..
