In Theory there is no difference between Theory and Practice. In Practice there is.
That reminds me of a joke.
A boy asks his dad, what is the difference between theory and practice?
The dad says, go ask your mom and sister if they would sleep with Brad Pitt for $1 Million.
The boy goes to mom and asks her if she would sleep with Brad Pitt for a $1 million and she says, “well I love your dad very much, but we could do so much for the family with $1 million, so yes I would sleep with Brad Pitt for $1 million.
Then the boy goes to his sister and asks her if she would sleep with Brad Pitt for a $1 million and she replies, “well I am not that kind of girl, but I could buy a car, finish college and move out on my own with $1 million, so yes I would sleep with Brad Pitt for $1 million.
The boy returns back to the father and the boy informs him that both his mom and sister would sleep with Brad Pitt for a $1 million.
The father responds and says that is the difference between theory and practice. In theory we live with two women, but in practice we live with two whores.
