From the popular (well, among font fondlers) TECHWR-L mailing list, Karen writes:
Four design engineers approached me with a wording problem. “We have multiple master clocks,” they said. “And one of them is more important than the others. There are also slave clocks, which are slaves to the masters. We call the most important master clock the Chief clock. Can we call the other master clocks Indians?”
The opening line reminded me of an old joke. A electrical engineer, a mechanical engineer and a software engineer are in a car, driving along the highway, when the car shudders and starts smoking. Pulling the car over to the should, the three discuss the problem.
The electrical engineer leans back in his seat, scratches his head and says “well, clearly it’s a problem in the car’s electrical system.”
The mechanical engineer disagress. “Clearly we have blown a gasket.”
They both turn to the software engineer for his opinion. He shrugs. “I don’t know what you guys are talking about. All we need to do is get out of the car and get back in again, and everything should be fine.”
Lame, I know.

I thought the punchline was that the software engineer said “All we need to do is close all the windows and shut the car down. When we restart it, it should work fine.”
Punch line: Upgrade.
