I got to thinking today, about that short-lived Cartoon Network Cartoon Cartoon Time Squad... I think that was just about the only cable cartoon series (that I can think of) that actually did a proper pilot episode; I'm not talking about one of those What A Cartoon! shorts that was later adapted into a series, but rather, they used the actual first episode of the series to set up the story, introduce the characters, and explain what the idea of the show was: in this case, we see how miserable Otto's life was at the orphanage, and how Tuddrussell and Larry 3000 accidentally warped into the orphanage, and end up "adopting" him, and explaining to him they're a Time Squad unit, who travels through time to resort history, since the longer time on earth progresses, the past begins to unravel and distort.
