The Difference between Theory and Reality.

One day little Jimmy was bored and went up to his father and asked
"Hey dad, whats the difference between theory and reality?" to which his father replied;
"Well, go ask mother if she would bang Tom Cruise for a million dollars"
Little Jimmy runs off and comes back a short time later
"Yup, she would"
"Ok, go ask your sister if she would bang justin bieber for a million dollars"
Little Jimmy runs off and returns
"Yeah, she would too"
"Well" says the dad, "So in theory we are millionaires but in reality we live with a bunch of whores"
