During class, a teacher trying to teach good manners asks the students,
one by one "Michael, if you were on a date, having dinner with a nice
young lady, how would you tell her that you have to go to the rest
room," she asked.

"Just a minute, I have to go pee", he said.

The teacher replied, "That would be rude and impolite. What about you
John, how would you say it?"

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

The teacher responded, "That's better, but it's still not very mannerly
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."

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 dinner."

The teacher fainted.
