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 you have to go to the bathroom?’

Michael said: ‘Excuse me, I need to pee.’

The teacher responded:  ‘That would be quite 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?’

Johnny said: ‘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 to  introduce you to after dinner.

The teacher fainted.
