Table manners

During class, a teacher trying to teach good manners asks the students,one by one -

"Michael, if you were on a date, having supper with a niceyoung lady, how would you tell her that you have to go to the bathroom?"she asked.

"Just a minute, I have to go piss."

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

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

The teacher responded, "That's better, but it's still not very nice tosay the word bathroom at the table."
"And you Little Johnny, are you able to use your intelligence for onceand 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 supper."

The teacher fainted.
