MacHack was an event that challenge developers to come up with some cool application in a 48 hour period. The events were held in Ann Arbor, Michigan from 1986 through 2003.
In 1996, a song, titled "Macintoshman" was created to play during a video montage of the previous year. The video was distributed via various Macintosh CD collections.
Here's a brief transcript of the song:
First time I saw it, I said come here quick. No DOS commands, I just point and click It got some icons and doddle and things Then I said the faithful words'How do I program this thing? Now I am a Macintosh man... Now I am a Macintosh man
