An English couple adopt a little German boy. After two years the child doesn't speak and the parents are worried about him. After three years he has not spoken and by his fourth birthday he still has not uttered a word.
The English couple figure he is never going to speak but he is a lovely child and on his fourth birthday they throw him a party and make him a chocolate cake with orange icing.
The parents are in the kitchen when the little German boy comes in and says, "Mother, Father, I do not like the orange icing on the chocolate cake."
My god," his mother says, "you can speak?"
To which the German boy replies, "Of course."
How come you have never spoken before? "his father asks.
"Well," the boy says, "up till now everything has been satisfactory."
