Remember the "good old days" when you were still using Windows XP? If so, I'm pretty sure you remember the loads of error dialogs that would pop up at a totally random time. Although these dialogs always show up at a bad time, you could do something pretty neat with them. Drag the window around and it would duplicate itself over and over!
Windows XP Error Dialog
Whoops - Looks like you were doing something very important. Since I don't like productivity, I'll just simply stop working leaving you with this useless error message.
But don't worry, I'll leave you something cool. Drag me around and see what's happening!
