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 the procedure for two weeks. The next time I see you, youll have lost at least five pounds.

When the blonde returns, shes lost nearly 20 pounds.

Why, thats amazing! the doctor says. Did you follow my instructions?

The blonde nods. Ill tell you, though, I thought I was going to drop dead that third day. From hunger, you mean? said the doctor.

No, from skipping, replied the blonde.
