"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?" the teacher asked. "Just a minute, I have to go pee", he said. The teacher replied," That would be rude and impolite. What about you, Paul, 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 Johnny, are you able to use your intelligence for once, and show us your good manners." With little hesitation Johnny said: "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."
