Potentially...Realistically

A little boy was supposed to figure out the difference between the words potentially and realistically. He decided to ask his dad since he was a rather smart man. His dad told him this, "Go ask your mother if she would have sex with George Cloney for one million dollars. Then go ask your sister if she would have sex with Brad Pitt for one million dollars. And finally go ask your brother it he would have sex with Johnny Depp. You will figure out the rest." So the little boy goes and asks his mother and she says, "Don't tell your father, but yes I certainly would." He then goes to his sister and she says, "Of course I would, he is so hot!" Finally the boy asks his brother and he says, "I guess I would for a million dollars." The little boy then returns to his dad and says, "I think I know what the difference is. Potentially we are sitting on three million dollars. When realistically we are living with two luts and a fag."
