Magic Pills
There is this lady and she is struggling having a baby so the doctor brings out these pills and he tells her each of these pills takes away a quarter of the pain and gives it to the father of the baby.
So she takes one and her husband says "Women must wimps, because I feel no pain."
Then she takes another and her husband says "Man this doesn't hurt at all."
So she takes two more and has no problem having the baby and neither she nor her husband are in pain.
Two days later they come home with the baby and the milkman is dead on their doorstep.
