A well-dressed man walks into a bar and asks a woman to sleep
with him for $1M. The woman is excited and she gives immediate
consent: "Of course I'll sleep with you!". 
Then the man asks, "will you sleep with me for $5?". The woman
indignantly replies, "Of course not! What do you think I am?".
The man replies, "We've already established what you are; now
we're merely haggling over the price."
