A teacher was teaching her class to use good manners.

She asks a student, "Michael, if you were on a date, having dinner with a nice young lady, how would you tell her that you needed to use the bathroom?"

He responded, "Just a minute, I have to go pee."

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 nice to use the word bathroom at the table. And you Peter, how would you show your good manners?"

Peter said with a smile, "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."
