I remember seeing this music video on adult swim when I was really young (this would’ve been around 2006-2007). It was animated in stop motion, and showed a bunch of toy soldiers shooting at each other in a desert. At the end of the video there’s only one toy soldier left, who shoots himself in the head, and then the song ends. All I can remember about the song itself is that it was sung by a male. I found it really disturbing, especially since I was too young to understand that cartoon network had ended. This means it most likely aired toward the beginning of the adult swim block.
This probably goes without saying, but no google/youtube searches have turned up anything. I even posted about this on r/tipofmytongue, but to no avail. The only reason I know I didn’t imagine the whole thing is because I have a friend who also remembers it. Any help is much appreciated!
