A goober was terribly 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 procedure for two weeks.  The next time I see you, you'll have lost at least five pounds."

When the goober returned, she had lost nearly 20 pounds.

"Why, that's amazing!" the doctor said.  "Did you follow my instructions?"

The goober nodded.  "I'll tell you, though, I thought I was going to drop dead that third day."

"From hunger, you mean?" asked the doctor.

"No, from skipping."
