A woman, pregnant with triplets, was walking down the street when a masked robber runs out of a bank and shoots her three times in the abdomen. Luckily, the babies were okay. The surgeon decides to leave the bullets in because it's too risky to operate. She gives birth to two healthy daughters and a son.
They were fine for 16 years, and then one daughter walked into the room in tears "What's wrong?" asks the mother.
"I was urinating and this bullet came out," replied the daughter. The mother tells her it's okay and explains what happened 16 years ago.
About a week later the second daughter walked into the room in tears. "Mom, I was urinating and this bullet came out." Again the mother tells her not to worry and explained what happened 16 years ago.
A week later, her son walk ed into the room in tears. "It's okay," says the mother, " I know what happened...you were urinating, and a bullet came out."
"No," says the boy, "I was masturbating and I shot the dog!"
