A woman pregnant with triplets was walking down the street one day when a 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 peeing 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 peeing and this bullet came out.' Again the mother explained.

A week later her son walked into the room in tears. 'It's okay' said the
Mom, 'I know what happened: You were peeing and a bullet came out.'

'No,' said the boy, 'I was playing with myself and I shot the dog.'
