A teacher was discussing morality with his young disciple who seemed slow to understand so he took him to a shop in the nearby market where robes where sold.

" Show me your very best robe, I am in a mood to spend excessively."

A most beautiful garment was produced and an extremly high price was asked for it.

" It is very much the thing that I am looking for but I would like some sequins around the collar and a touch of fur trimming."

"Nothing easier said the merchant for I have just such a robe in my work room." He disappeared for a few moments and then returned having added the fur and sequins to the self-same garment.

" And how much is this one?"

Twenty times the price of the first one," said the shopkeeper.

" Excellent, I shall take them both."
