This is, by far, my second moment in the whole show (the first being the scene where Spike was left on that floating iceberg). The moment when Sludge revealed to this idiot that he isn't his dad and he makes this face when he fully realizes what's happened. What made this even more satisfying for me was when I realized, while I was making this, that Sludge never got a punishment for what he did and Spike never found his true parents. If I had seen that episode when it had first aired, I would've sent the writers a thank-you card for this.
