During one of her daily classes, a teacher, trying to teach good
manners, asked her students the following question: "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 bathroom?"
Michael said, "Just a minute I have to go pee."
The teacher responded by saying, "That would be rude and impolite. What
about you Peter, how would you say it?"
Peter said, "I am sorry, but I really need to go to the bathroom. I'll
be right back."
"That's better, but it's still not very nice to say the word bathroom
at the dinner table. And you, little Johnny, can you use your brain 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.
