A married couple rushed to the hospital because the woman was in labour.
The doctor asked the couple, "I have invented a new machine that you might want to try, it takes some of the labour pains away from the mother and gives it to the father." So the married couple decided that they would try this.
The doctor hooked the machine up and put it on 10% of pain switched from the mother to the father. The husband said "I feel okay, turn it up a lot more". So the doctor turned it up to 50%. The husband said "why donít you just put it all on me because Iím not feeling a thing". But the doctor warned him "this much could kill you if you're not prepared". The husband replied "I am ready" so the doctor turned the machine up to 100%. But the husband still didnít feel a thing. The couple and their new baby later went home happy after the pain free labour.
When they got home they found the Postman dead on the front step.
