The polite way to say I have to pee

During one of her daily classes, a teacher trying to teach good manners decided to quiz her male students to see how they would handle this question. 

She was a little concerned as to the responses she could get from some of the men in the class but decided to pursue the question anyway.

Here is what happened.

“Gentleman, how would you announce to your dinner date that you have to go to the restroom?”

“What about you 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 Sherman, how would you say it?”

Sherman 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 who I hope to introduce you to after dinner.’”

The teacher fainted.
