Bertha was very depressed. Her husband of 50 years had just commited suicide the day before. She decided that she would join her husband by killing herself. The only problem was, she had to think of where to shoot herself so it would end up killing her.
Bertha drove over to her doctor's office and asked him where your heart is. He told her right below the left breast, so she went home.
Bertha grabbed her husband's gun and shot her left knee.
