A Software guy, a Hardware guy and a Mainframe guy are driving across the desert when they get a flat tire. The Mainframe guy says, "Well, now we have to get a new car."
The Hardware guy says, "I got a better idea. Let's rotate the tires and see if we can isolate the problem."
The Software guy says, "Nah, let's run it another thirty miles and see if the problem reoccurs."
