Bullets

 

A woman pregnant with triplets is walking down the street when a masked  robber runs out of a bank and shoots her three times in the stomach. Luckily the babies are okay. The surgeon decides to leave the bullets in because it's too risky to operate.

All is fine for 16 years until one daughter walks into  the room in tears."What's wrong," asks the mother.
"I was having a wee and this bullet came out," replies the daughter. The mother tells her it's okay and explains what happened 16 years ago. About a week later, the second daughter walks in to the room in tears. "Mom, I was having a wee and this bullet came out". The mother tells this daughter not to worry and explains what happened 16 years ago.

 A week later the boy walks into the room in tears. "It's okay," says the mom,"I know what happened, you were having a wee and a bullet came out.""No," says the boy, "I was jerking off and I shot the dog."
