I most often missed out on Saturday morning cartoons entirely as a kid, but it wasn't by choice. My mom worked every Saturday morning, and I always ended up having to go with her to work. The cool part was that she usually took me to the mall or to some other store afterwards, often buying me a toy or getting me something to eat while we were out. The downside was that I missed out on Saturday morning cartoons most of the time because I usually wasn't allowed to go into the area of her workplace that had the TV.
Whenever I did get a chance to watch Saturday morning cartoons, though, I pretty much stuck with whatever was airing on Fox Kids at the time. That was the block that I watched whenever I got home from school during the week, so that was the block that most interested me at the time.
