During an etiquette class, a teacher is trying to teach her students good manners to follow while on a dinner date.

"Michael," she asks one of the students, "if you were on a date, having supper with a nice young lady, how would you tell her that you have to go to the bathroom?"

"Just a minute," replies Michael, "I have to go p*ss."

"That would be rude and impolite!" exclaimed the teacher. "What about you, John, how would you say it?"

"I'm sorry," answered John, "but I really need to go to the bathroom. I'll be right back."

"That's better," said the teacher, nodding, "but it's still not very nice to say the word 'bathroom' at the table.

And you, Peter, are you able to use your intelligence for once and show us your good manners?" she asked.

Peter smiled and responded, "I would say, 'Darling, may I please be excused for a moment? I have to shake hands with a very dear friend of mine, whom I hope you'll get to meet after supper.'"

The teacher fainted.
