A blonde is overweight, so her doctor puts 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 blonde returns, she's lost nearly 20 pounds.
"Why, that's amazing!" the doctor says.
"Did you follow my instructions? "
The blonde nods.
"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 all that skipping."
