First Aid

A lady had just finished doing her CPR course and was on the lookout for
a chance to try it out.  As she left the shopping centre she saw a man
lying on the floor with a lot of people around him.  Screaming "I know
first aid!" she ran to the person, threw her bag down, loosened all tight
clothing a got ready to start mouth-to-mouth.

A this stage a huge policeman tapped her on the shoulder and asked, "Do
you mind, I'm trying to arrest this man."
