It helps if you see the original (hi-definition) trailer first, but either way fans of the eternal Batman/Joker rivalry will appreciate this.

About three weeks ago, Warner Brothers began a phase of their Dark Knight viral marketing campaign where teams of 300 gathered in 12 different cities to hunt throughout their respective domains, counting things like trees and stairs according to their appropriate instructions. Along the way, they were to gather information needed to unlock an online safe, and ultimately be rewarded with the then-unreleased Dark Knight trailer in a local theater.

One winner in each of the 12 cities also received a 35mm print of the new trailer- a nice surprise, especially considering studios rarely hand out film prints. But there was something unusual about these prints. Apparently, every last frame had been defaced (by hand!- thumb prints on the film to prove it) by the Joker.

Take a look:

Yes, that is a light saber you see at one point. It really is hilarious to think of the Joker sitting there yawning through the trailer scribbling things like “BORING PART” across the screen until his own mug shows up- at which point he lights up and draws dozens of arrows pointing at himself, effectively blocking out the rest of the scene. It’s so maniacally in character.
