I've watched this thing like 10 times...
...and it still hasn't gotten old. I'm singing the "Zombie Jamboree" song in the shower, and I'm still laughing at the humor. Really a job well done. While the first one was good, and left me horrified yet sympathetic to the poor kid's choice of action, this one is by far the better of the two, and has been given the status it deserves by fans across Newgrounds.
Please DON'T make gone too far three, as I can't possibly see it getting any better than this. I'd hate to expect too much and have you Go Too Far to make it funny or likable and be disappointed.
Excellent animation, and I would love to see more UNRELATED work.
