Benny wanted a job as a signalman on the railways.
At his interview, the inspector asked him this question:
"What would you do if you saw 2 trains heading for each other on the SAME track?
Benny replied," I would switch the points for one of the trains."
"Good. But what if the lever broke?", asked the inspector.
"Then I'd run down to the signal box", said Benny, "and use the manual lever there."
"What if lightning struck it?' asked the inspector.
