Train Test

Tom is applying for a job as a signalman for the local railroad and is told to meet the inspector at the signal box.
The inspector decides to give Tom a pop quiz, asking: "What would you do if you realized that two trains were heading towards each other on the same track?"
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 down there", answers Tom.
"What if that had been struck by lightning?" challenges the inspector.
"Then," Tom continued, "I'd run back up here and use the phone to call the next signal box."
"What if the phone was busy?"
"In that case," Tom argued, "I'd run to the street level and use the public phone near the station".
"What if that had been vandalized?"
"Oh well," said Tom, "in that case I would run into town and get my Uncle Leo".
This puzzled the inspector, so he asked, "Why would you do that?"
"Because he's never seen a train crash."

3D movies

In 1953, the first 3D motion picture produced and released by a major company, Man in the Dark, opened at the Globe Theater in New York City, starring Edmond O'Brien. The next 3D feature movie, The House of Wax, was the first from a major company in colour and opened only two days later, at the Paramount Theater in NYC. The idea, however was not new. The first 3D feature film, The Power of Love, made in the U.S. by Perfect Pictures in 1922, used the familiar method of providing to the audience spectacles with one red and one green lens to produce the illusion of depth. The first 3D talking picture in colour, a Russian production of Robinson Crusoe, was shown in Moscow in Feb 1947.
