Triplets

A woman pregnant with triplets was walking down the street when a
masked robber ran out of a bank and shot her three times in the stomach.
Luckily, the babies were OK. The surgeon decided to leave the
bullets in because it was too risky to operate. She gave birth to two
healthy daughters and a healthy son. All was fine for 16 years, and then
one daughter walked into the room in tears.
"What's wrong?" asked the mother.
"I was taking a tinkle and this bullet came out," replied the daughter.
The mother told her it was okay and explained what happened 16 years
ago.
About a week later the second daughter walked into the room in tears.
"Mom, I was taking a tinkle and this bullet came out." Again the mother
told her not to worry and explained what happened 16
years ago.
A week later her son walked into the room in tears. "It's okay" said the
Mom, "I know what happened. You were taking a tinkle and a bullet came
out."
"No," said the boy, "I was playing with myself and I shot the dog."
