A little boy comes up to his father, and asks "Daddy, what's the difference between 'in theory' and 'in practice'? I've heard it a couple times, and I don't get it"
The father replies "Son, that's a tough question to answer... let me show you an example, and maybe you can figure it out for yourself..."
"Here's what you do, go into the kitchen, and ask your mother if she'd sleep with a stranger for 2 million dollars."
The son starts to question, "But dad, that doesn't..." and the dad cuts him off, "just go do it son, and come back and tell me what she says".
So the little boy goes to his mom, and asks her, and she replies "wow, that's a tough one, let me think about it... yes...I'd have to say yes, for 2 million, I would"
The boy runs back to his father, and tells him what his mom says, and the father replies "All right, now go ask your sister the same questions..."
The son starts to question, "But dad, that doesn't..." and the dad cuts him off, "just go do it son, and come back and tell me what she says".
So the boy goes and finds his sister, and asks her the same question. Immediately she replies "hell yeah, for 2 million I'd do it in a heartbeat!"
The boy runs back to his father, and tells him what his sister said. THe father smiles and says "And what have we learned? Do we understand what 'in theory' and 'in practice' mean?"
The boy thinks about it for a second, and replies "I think I get it now dad..
"In Theory, we're sitting on 4 million dollars"
"In Practice, we just live with a couple of whores"
