A Company Develops A Machine For Evaluating IQ.

The scientists developing it asks for the help of the supervisor, manager and president of the firm to test the machine.

When the supervisor places his head on the machine, it responded: 'IQ 160', and he was very impressed.

When the manager places his head on the machine, it responded: 'IQ 170', and he was very impressed.

When the president placed his head on the machine, it hummed for a bit and responded: 'this is a very sensitive machine, please do not use rocks as test subjects', and the president is furious.

After hurried improvement, the scientists ask the three to try again. This time the machine gave the manager an IQ of 165, the supervisor an IQ of 170 and both were very happy, saying it was more accurate.

After the president places his head on the machine, it hummed for a bit and responded: 'this is a very hot rock', and the president was furious, threatening to fire the scientists.

After a third improvement phase, the scientists assured everyone that the machine was perfect. This time, the supervisor was given an IQ of 170, and the supervisor and IQ of 175. Both praised the machine stating that it was perfect and urged the president to try again.

Having learned from his past mistakes, this time the president decides to place the rock onto the machine first. After some humming, the machine responded: 'Welcome Mr president!'.
