Microsoft Support

A Microsoft support man goes to a firing range. He shoots 10 bullets at the target 50m away. Then the supervisors check the target and see that there's not even a single hit, and they shout to him that he missed completely. So he tells them to recheck, and gets the same answer. Then he put his finger at the top of the gun and shoots, blasting off his finger. When he saw it he shouted back "I don't know, it's working perfectly here, the problem must yours..."

Integrated circuit

In 1964, a U.S. patent was issued to Jack S. Kilby for his invention of “Miniaturized Electronic Circuits” now known as integrated circuits (No. 3,138,743, filed 6 Feb 1959), which he assigned to his employer, Texas Instruments, where he worked. With it, he created a new way of reducing the space taken up by an electronic circuit by which “all components of an entire electronic circuit are integrated into the body of semiconductor material,” for which he used germanium. Geoffrey W.A. Dummer also had the concept years earlier, but never completed a working device. A few months after Kilby's demonstration in 1964, an IC device in an improved form was independently invented by Robert Noyce at another company. Eventually, the two companies agreed to cross-license their patents.«
