So I watched The Melancholy of Haruhi Suzumiya today, and noticed that if you pay attention to Haruhi herself, she states that the correct order for the episodes is:
2,3,5,10,13,14,4,7,6,8,1,12,11,9
If you watch them in that order, you'll find that that is indeed the real order for the episodes...
So why would they randomize them like that in the first place?
