A woman is shot in the tit 3 times and rushed to hospital.
When she finally awakes, the doctor sits her up and says
"I'm afraid I have some bad news. In order for you to live, we must remove your damaged breast. If we do not do so, you will die"
"Never!" the woman replies. "I can't go around with just one breast. Ill take the risk"
So after being suitably patched up, she goes on her way, and after a couple of weeks she reports back to her doctor that she is still alive.
"Well that is indeed good news, however you will now have to live with those 3 bullets inside your breast for the rest of your life."

The woman accepts this and goes on to have a family of 3 children, 2 daughters and a son.

One day, one daughter comes down and tells her mum that whilst having a wee, a Bullet emerged.
The mother runs her child through the incident and explains how it occured.

Another day, the other daughter comes downstairs and tells mum that whilst having a wee, a Bullet emerged.
Again, the mother explains the incident.

Soon afterwards, her Son comes downstairs.
"Don't tell me" the mother says. "You were having a wee and..."
"No mother. I was having a wank and I've just shot the cat"
