L15-2：Fifty pence worth of trouble
On his way to the sweet shop, he dropped his 50 pence and it bounced along the pavement and then disappeared down a drain. George took off his jacket, rolled up his sleeves and pushed his right arm through the drain cover. He could not find his 50 pence piece anywhere, and what is more, he could not get his arm out.
A crowd of people gathered round him and a lady rubbed his arm with soap and butter, but George was firmly stuck. The fire brigade was called and two fire fighters freed George using a special type of grease. George was not too upset by his experience because the lady who owns the sweet shop heard about his troubles and rewarded him with a large box of chocolates.
