A kid says to his father before he goes downstairs to play some pinball, "Pop, what's the difference between theory and reality?"
        His father says, "Go ask your mother if she'd have sex with the mailman for a million dollars."
        The kid comes back and says, "She said yes."
        His father says, "Go ask your sister if she'd have sex with the neighbor for a million dollars."
        The kid comes back and says, "She said yes."
        His father says, "Okay. So, in theory, we're rich. The reality is, we live with a couple of whores."
Now, let's go play some Scared Stiff!

Professor Higgins at the University of Sydney was giving a lecture on ‘Involuntary Muscle Contraction’ to the first year medical students.
This was not an exciting subject and the professor decided to lighten up the mood.
He pointed to a young woman in the front row and asked, ‘Do you know what your asshole is doing while you’re having an orgasm?’
She replied, ‘Probably playing pinball with his buddies.’
