A blonde is terribly overweight, so her doctor put her on a diet. "I want
you to eat regularly for 2 days, then skip a day, and repeat this procedure
for 2 weeks. The next time I see you, you'll have lost at least 5 pounds."
When the blonde returned, she shocked the doctor by losing nearly 20
pounds. "Why, that's amazing!" the doctor said, "Did you follow my
instructions?" The blonde nodded... "I'll tell you though, I thought I was
going to drop dead that 3rd day."  "From hunger, you mean?", asked the
doctor." No, from skipping."
