There was blonde who wanted to go on a diet. She went to the doctor
and asked for his advice. He said that she was going to go on a diet
for three days
"Eat anything and everything you want for the first two days of your
diet. Then skip the third day."
So the blonde went home and ate anything and everything she wanted for
the first two days, then she skipped the third day.
The next day she went back to the doctor and he asked her, "How is
your diet?"
She said, "Well, the first two days were easy but that third day was
hard. Doing all that skipping made me really tired."
