Original Sin

There was this hooker who mistook a Salvation Army man for a soldier and propositioned him. The Salvation Army gent said, "Ma'am, you may be forgiven, as a pitiable victim of circumstances. Tell me, are you familiar with the concept of 'original sin'?"

The hooker replied, "Well, maybe and maybe not. But if it's "really" original, it'll cost you an extra $20."
