Years ago when I was younger than currently I got this first summer job as help in IT departament to answer calls from distressed workers.

Once this lady calls that "her monitor went black" and she cannot work, so I have to get her a replacement. They got only this big heavy CRT monitors as replacements so I had to drag it to 4th floor (no elevator) from basement.

As I reached her it turned out that her monitor is fine, only the wallpaper was changed to black, that what she was meaning :p

Well, at least I got some exercise back then.
