A blonde is overweight so her doctor put her on a diet.
"I want you to eat regularly for two days," he tells her. "Then skip a day and repeat the 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 forty pounds. "Why that's amazing," the doctor says. "Did you follow my instructions?"
The blonde nods. "I'll tell you what though, I thought I was going to drop dead that third day."
