Little Johny asks his dad the difference between theory and reality.
Dad says: Go ask your mother if she would sleep with anyone for a million dollars. Johny runs off and asks his mom and comes back. “She said yes!”
Dad says: Now go ask your sister. Johny comes back and says “She said yes!”
Dad tells Johny: In theory we have 2 million dollars.
In reality we live with two whores.
