From eviljaymz.com (site seems to have vanished now, though :( ), reasons why people who work with computers seem to have a lot of spare time:
Web developer: "it's uploading"
Sysadmin: "it's rebooting"
Hacker: "it's scripted"
3D artist: "it's rendering"
IT consultant: "it's your problem now"
Programmer: "it's compiling"
