儿童笑话|Going To The Toilet

During a good manners and etiquette^{1 class being held for young children, the teacher says to her students:
If you were courting a well educated young girl from a prominent2 family and during a dinner for two you needed to go to the toilet, what would you say to her?
Mike replies: Wait a minute, I'm going for a piss.
The teacher says: That would be very rude and improper3 on your part.
Charlie replies: I'm sorry I need to go to the toilet, I'll be back in a minute.
The teacher says: That's much better but to mention the word ''toilet'' during a meal, is unpleasant.
And Little Johnny says: My dear, please excuse me for a moment. I have to go shake hands with a personal friend, whom, I hope to be able to introduce to you after dinner.}
