This weeks joke told by : John Cusock Tom is being interviewed for a job as a railway signalman. The inspector quizzes Tom,asking, " what would you do if you realised that two trains were about to collide?" Tom says, "I would switch one train to another track " "what if the lever broke?" asks the inspector. " Then I'd run down to the tracks and use the manual lever that's there," replies Tom. "What if that had been struck by lightning?" "Then,' Tom continues, I'd come back and use the phone to call the next signal box." "What if the phone was busy?" presses the inspector. "In that case,.' Tom argues, I'd use a public phone." and what if that was broken? " Oh, well,' says Tom, I'd run and get my Uncle Leo." " Why would you do that?" asked the puzzled inspector. " Because he's never seen a train crash.'
