Cheese or Sardine

An excited girl telephoned the doctor."Doctor,doctor,my brother swallowed a mouse.What shall I do?"
"Wave a piece of cheese in front of his mouth until I get there."
Fifteen minutes later the doctor arrived at the girl's house.He found that the girl was waving a sardine in front of her brother's mouth.
"I said a piece of cheese,not sardine!"exclaimed the doctor
"I know you did,"the girl replied. "But,I have to get the cat out first"
