A salesman called on my wife the other day and tried to sell her a freezer. You'll save a fortune on your food bills, he promised. I can't tell you how much you'll save. It'll be tremendous. Said my wife: I'm sure you're right, but we're already saving a fortune with our new car by not taking the bus. We're saving a fortune with our new washing machine by not sending out the laundry. We're saving a fortune with our new dishwasher by giving up the maid. The plain truth is that right now we just can't afford to save any more!
