A blonde woman was overweight, so her doctor put her on a diet. "I want you to eat regularly for two days, then skip a day, and repeat this for two weeks. The next time I see you, you'll have lost at least five pounds."
When the blonde returned, she had lost 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 on the third day."
"From hunger, you mean?" asked the doctor.
"No," replied the blonde. "From skipping."
