Find a joke called "This stone looks familiar"

It is said that a scientific research group in a certain country developed a new instrument one day. This instrument is specially designed to test people's IQ.

One day, the presidents of this country, A and B, and a prime minister, C, came to the experimental base. Principal a said, let's try. So the three of them started the experiment. Chairman A put his head into the machine, and the machine said, "Your IQ is 122." Chairman B also put his head in, and the machine said, "Your IQ is 124." At this time, Premier C smiled happily. "My IQ is higher than both of them." Then the Prime Minister put his head into the machine, and the machine said, "Please don't make fun of stones." C's face became ugly at once, and everyone in the research group thought it was too bad and humiliating for the prime minister. They dare to explain that "this is just developed and needs to be improved." So the three changed and left.

A few months later, after improvement by the development team. The three men came to the institute again and conducted another experiment. Chairman A put his head into the machine, and the machine said, "Your IQ is 122." Chairman B put his head into the back of the plane and said, "Your IQ is 124." At this time, it was Premier C's turn again, and he also put his head in. Then the machine said, "Please don't joke with the stone, but this stone looks familiar!" "
