One day, a young pregnant woman was waiting in line at the bank when
it was robbed.  During the robbery, she was shot three times in the
stomach.  She was rushed to the hospital where doctors saved her life.
As she was leaving, she asked the doctor about her baby.
     
The doctor said, "Oh You're going to have triplets.  They're fine, but
each one has a bullet lodged in its stomach.  Don't worry though, the
bullets will pass through their system through normal metabolism."
     
As time went on the woman had three children.  Two girls and a boy.
Twelve years later, one of the girls came up to her mother and said,
"Mommy, I've done a very weird thing!"
     
Her mother asked her what happened and her daughter replied, "I passed
a bullet into the toilet."  The woman comforted her and explained all
about the accident at the bank.
     
A few weeks later, her other daughter came up to her with tears
streaming from her eyes.  "Mommy, I've done a very bad thing!"  

The mother said, "Let me guess.  You passed a bullet into the toilet,
right?"

The daughter looked up from her teary eyes and said, "Yes.  How did
you know?"  The mother comforted her child and explained about the
incident at the bank.
     
A month later the boy came up and said, "Mommy, I've done a very bad
thing!"

"You passed a bullet into the toilet, right?"
     
"No, I was masturbating and I shot the dog."
