Andy wanted a job as a signalman on the railways.
The inspector asked him this question: "What would you do if you saw 2 trains heading for each other on the SAME track?
Andy said," I would switch the points for one of the trains."
"What if the lever broke?", asked the inspector.
"Then I'd dash down to the signal box", said Andy. "And use the manual lever there."
"What if lightning struck it?' asked the inspector.
"Then..." Andy continued, "I'd run back into signal box and phone the next signal box."
"What if the phone was engaged?"
"Well.....in that case," perservered Andy, " I'd rush down out of the box and use the PUBLIC emergency phone at the level of the crossing up there..."
"What would you do if THAT was vandalized?"
"Oh, well then I'd run into the village and get my Uncle Brown."
This puzzled the Inspector, so he asked, " Why would you do that???"
"Because he's never seen a train wreck !!"
