An elderly gentleman and a very attractive young lady are sharing a sleeping compartment on a train for a very long journey. They talk about many things, Sport, Politics, Religion and are getting on very well. Eventually they get on to discussing Sex and Morals.

The man asks the young lady if she would go to bed with him for £10 million pounds.
She quickly replies "Why yes."

He then asks would she go to bed with him for £1 million pounds.
Again but with a little hesitation she says "YES."

He asks a third time. Would she go to bed with him for £10 ?

With no hesitation she replies "NO! What sort of girl do you think I am?"

He replies "We have already established that. All we are doing now is haggling over the price!"
