While working as a Clean-up animator on Barnyard, we provided help animating some BG characters, I was given the wrong direction ( BUMMER) when doing my shot, so as a result it had to get changed, but my supervisor liked it enough to let me keep the shot for my own, because I had a ton of other fixes to do on the show, it left no time for me to redo the shot, so one of my fellow co-workers got to re-aniamte the scene.
