Basically, this is intended to be an adult-oriented animated series. You can tell it's adult-oriented because of the language they sprinkle liberally throughout the dialog. I don't know why they do this - it adds nothing to the humour, and it means that parents won't want their kids to watch and some adults will be offended by the language, resulting in a diminished audience.
If the viewer wants adult-oriented humour, there are plenty of non-animated shows around (example: the late, lamented Santa Clarita Diet) that can fill the bill. There are also lots of "regular" animated shows with a lot more humour in them.
