|Marty arrives home from work and as soon as he sets foot in the house, Sadie is on to him, telling him that their friend Marvin has finally quit smoking.|
"Imagine that, Marty," she says, "someone who smoked 3 packs a day for 20 years has stopped smoking all of a sudden. Now that's what I call will power - something that you definitely don't have."
But Sadie hadn't finished.
"And that's not all. I hear that Bernie, that drunken friend of yours, is finally giving up drinking - another example of the kind of will power that you don't have."
"OK, Sadie," said Marty, "you want to see will power, do you? Well here's will power. I am going to sleep in the spare room from now on. I am going to prove to you that I won't be affected at all by not sleeping with a woman."
Marty keeps to his word.
One night, when he had been sleeping alone for a week, there is a knock on his bedroom door.
Marty shouts out, "What do you want?"
Sadie replies, "Marvin has started smoking again."
