So this guy walks up to to a woman in a bar and says, "Would you have sex with me for $100?"
She slaps his face and says "No"
He says, "How about a million?" She thinks a second and says "....maybe..."
He says, "How about $250?"
She says, "What do you think I am, a prostitute?"
He says, "We've already determined that you're a prostitute. We're just haggling over price."
