When you are faced with a choice of two different buttons, one that could lead to the salvation of earth, the other, its destruction. But you don't know which one is which.
When your face is slammed into your keyboard and you are transported into a magical world of magical talking ponies that look very different from the ones you are used to seeing
When you go out trick-or-treating and every house you go to has a dentist living there and all you get are toothbrushes!
That's Helen Keller, if you did not know. When your computer catches fire and you have a bad case of muffinitis.
