Once there were two sisters named Annie and Jenny. One day they were cycling. Suddenly, Annie lost her balance and fell down and started crying. Jenny helped her in getting up and took her home

At home, their mother bandaged her and asked their father to take Annie to a doctor for a tetanus injection.

On hearing the name of injection, Annie immediately went to the kitchen and took out an apple from the refrigerator.

Just then Jenny came into the kitchen and asked Annie whether she was scared of injection. At this Annie replied, "Yes, I am afraid of injection. That's why I am eating this apple. Didn't our teacher say that an apple keeps the doctor away?"
