Bank robbery
A Woman, pregnant with triplets was a bystander near a bank robbery. The robber shot her three times in the stomach. No great damage was done but the surgeons thought it was too risky to operate so they let things take their course. She subsequently gave birth to 2 girls and a boy, all healthy.
Many years later, in their teens one of the girls came crying to mother. She said "I was having a tinkle when this bullet fell out" Mother told her not to worry and related the story. A day or so later the other daughter came crying with the same story and was told the story A day or so later she went into the boy's bedroom to find him crying his eyes out.
Dont worry she said I know all about it. You were having a tinkle and a bullet fell out.
No! said the boy. "I was playing with myself and I shot the dog"
