FRANK applies for a job as a signalman on the railways, and is told to meet the inspector at the signal box.
“What would you do if you noticed that two trains were heading towards each other on the same track?” the inspector asks.
“I would switch one train to another track,” Frank replies.
“What if the lever broke?”
“Then I’d run to the tracks and use the manual lever there.”
“And what if that had been struck by lightning?” the inspector counters.
“I’d run back up here and phone the next signal box,” Frank replies.
“What if the phone was being used?”
“Well, in that case I’d run out to the street and use the phone box near the station.”
“What if that phone had been vandalised?”
“Oh well,” Frank replies, “in that case I would run into town and get my Uncle George.”
The inspector is flummoxed. “Why would you do that?”
“Well, he’s never seen a train crash.”
