It's from a time before StackOverflow (and StackExchange at large) got very ridged with all the rules. Back then, there were a lot of "fun" questions and answers, including the infamous "What is the best comment in source code you have ever encountered?"[1]

Some old timers might remember those days... SO was a much more fun place back then. Now it's rife with down-voters, close-voters and hostile-towards-newbie folks.
