TOPIC: what's the difference between hypothetical and rea

Little Johnny asked his dad what is the difference between hypothetical and realistic.
Dad: go ask your mother if she would sleep with a stranger for a million dollars.
Johnny: she said yes I still don't understand.
Dad: Go ask your sister the same thing.
Johnny: she said yes. I still don't understand.
Dad: Hypothetically you live with 2 millionaires realistically you live with 2 whore's

Lol, ouch!
