Mr. Johnson was overweight, so his doctor put him on a diet. He said; "I want you to eat regularly for two days, then skip a day, and repeat this procedure for two weeks.
The next time I see you, you should have lost at least five pounds." When Mr. Johnson returned, he shocked the doctor by having dropped almost twenty pounds. "Why, that's amazing!" the doctor told him. "You did this just by following my instructions?"
The slimmed down Mr. Johnson nodded. "I'll tell you, though, I though I was going to drop dead that third day." "From hunger, you mean?" "No," replied Mr. Johnson, "from skipping."
