Mr Tall telephoned the doctor in the middle of the night.
"Come quickly，Doctor.You know that my wife sleeps with her mouth open.Well，a mouse has run down inside her！"
"I will be with you in about ten minutes，"replied the doctor."Un-
til I arrive，try holding a piece of cheese in front of her mouth.This may bring'the mouse out."
When the doctor arrived，Mr Tall was not holding a piece of cheese.He was holding a fish in front of his wife，s mouth.
"What are you doing？"asked the doctor."Mice don't like fish."
"I know，"said Mr Tall，"but we have to get the cat out first."
