Yea, definatly a cruel joke. I didn't even know that was there. But if the person is smart and just fixed it, that would ruin your fun of seeing them get pissed at the computer and maybe hitting it?!
Change the desktop resolution to 1920xwhatever and hit Y while the monitor says out of range. And if you edit msdos.sys to not allow safe mode...
Maybe that's just cruel.
