Question #67 and 68

67: In the movie Ella Enchanted, she is cursed to be obedient. For example, if someone told her to eat an apple, she would have to eat that apple. Why didn't anyone say "cure cancer in 6 seconds" or "find a way to bring the dead back to life by tomorrow". Wouldn't those commands have been useful?

68: Why is facebook called facebook? It isn't a book and doesn't really have anything to do with your face. besides your profile picture...
