When Fred Forgot To Tell His Mom He Was Going Outside.
In one episode from the post 79 episodes he mentions as a kid forgetting to do that and his mom punished him for it.
What's funny about it is he seemed emotional over it at the time the episode was produced cause he seems to have a gleam in his eye or eyes. Which seems odd to me because it was like he never got over it and most people who would have done something like that wouldn't have been so upset over their behavior long after they grew up.
I wonder why that was the case with him?
