What I really hate, is when you try to install something, and you see an error, and the instructions tell you to "contact your system administrator" or "software provider" - seriously, I feel like ripping out the eyeballs of who ever made up that cope out. It's like saying, "Umm... we don't know the answer so contact anyone but us. "
hahahahhahahahah yeah. that can be a real pain the butt. my favorite errors are ones that want you to send into microsoft in an error report.
like my dad was working on program one day, and was running Mac's iTune in the background for some testing, and it of course crashed (being that it was mac software) my dad got the would you like to send an error report, he of course did because he thought it would be funny to see the faces of the microsoft tech employees reading a macintosh program crash report. i got a good chuckle out of it.
