He has an assignment to find out what the difference between hypothetical and realistical is.

So he asked his dad and his dad said, "Well, go ask your mom if she would sleep with the mail man for one million bucks."

So Little Johnny went and asked his mom and came back and said, "She said yes."

"Well," said the dad, "Go ask your sister the same question."

He did and came back and said, "She said yes."

And the dad said, "Now go ask your brother the same thing."

He did and came back and said, "He said yes too!"

And the dad said, "Well hypothetically we're sitting on three million dollars, realistically we're living with 2 whores and a fag!"
