A family of tortoises went into a cafe for some ice cream. They sat down and were about to start when Father Tortoise said, I think its going to rain. Junior, will you pop home and fetch my umbrella? So off went junior for Fathers umbrella, but three days later he still hadnt returned. I think, dear, said Mother Tortoise to Father Tortoise, that we had better eat juniors ice cream before it melts. And a voice from the door said, If you do that I wont go.
