A boy asks his father the differences between realistic and hypothetical situations?

The father says, "Ok son, firstly go ask your mother if she would have sex with George Clooney for a million dollars, then ask your sister if she would sex with Brad Pitt for a million dollars, and lastly ask your brother if he would sleep with Brad Pitt for a million dollars." The boy goes to his mother and the answer she gives is, "of course I would have sex with George Clooney for a million dollars." The boy goes to his sister and she says, "of course I would have sex with Brad Pitt for a million dollars." Finally, the boy goes to his brother and his brother says "yeah I suppose I would have sex with Brad Pitt for a million dollars, that is a lot of money." The boy goes back to his father and reports back what everyone has said to him. The father says, "well son hypothetically we are sitting on three million dollars right now. Realistically we live with two whores and a faggot."
