Long intros... Well, some can be quite effective as a lead-in. This one, just above, in my opinion is very effective:

If I don't like an intro to a video I'm posting on YouTube, I just add a piece of jump-to code to the end of the link -  for those unaware of it, adding &t=25 to the end of a YouTube link will cause the video to start 25 seconds into the video. Unusually, I cut nearly two and a half minutes from the intro start of this one...
