cure for blindness

A little blind girl goes up to her mum and says, "Mummy, mummy, when
will I be able to see?" Her mum replies "I'll tell you what, I'll take
you to the chemist and get you some special cream for your eyes and
you will be able to see in the morning." So off they went to the
chemist, got the cream, and went home, all the while the little girl
was getting more and more excited at the prospect of being able to see
again. Once they got home, the mother put the cream on the little
girls eyes, wrapped a bandage around her head, and took her to bed.
The following morning the little girl stumbled into her mums bedroom
and excitedly shouted "Quick mummy, take off the bandage so that i
will be able to see again." So the mother slowly took of all the
bandages, taking her time, and all the while the little girl was
getting more and more excited. Once they were off the little girl said
"But mummy, I still can't see." To which the mother replied, "April
fool!"
