Something that will always amuse me is that Hugo was in the show's production before Tina was.
Really think about that for a second. Hugo was in the show's pilot but Tina wasn't. Instead, the oldest Belcher kid was a boy named Daniel. Same voice actor, mostly the same lines but not the same character.
Now, the pilot (or demo or whatever you wanna call it) came out in 2009 but still. Loren and his team of writers must have spent months maybe even years thinking of the character of Daniel Belcher, coming up with storylines and characters he would interact with only to then throw all that away when they decided to replace him with Tina. Not only Daniel but many other ideas that the writers had when developing this show were put to the side before it even aired. It's quite amazing that minor, seemingly unimportant characters like Hugo survived the cutting board process while a main character like Daniel didn't even though the writers must have come up with him pretty early in the show's development.
It's something I often remind myself of as I'm developing my own stories. No matter how long I've had an idea (whether it's a plot point or a character) there's no reason to be married to them. No matter how big or how small I can always change them or get rid of them entirely for the sake of a better end-product.
