A man approached a hooker and said "I'll give you $500 if you will have sex with me anyway I want.  The Hooker said that the price he offered is slightly low.  The man then said "Well then I’ll give you $1000 if you will have sex with me anyway I want.  The hooker finally agreed and they left and went to a motel.

The hooker and man were busy at it when suddenly the hooker said "Exactly how do you want to have sex for $1000?”  The man replied, "On Credit Baby...On Credit!"
