I already figured it out. BY CHEATING! Here's how I did it:

Each wrong answer video has a different ending, but he never uses the same link once for each answer. Since the annotation shows the link to the video when you mouse over it, I wrote the first few letters of each video's "number code", then crossed it out when I see the link twice. The one that was left was the right answer. And yes, I thought it up myself. :D
