It's seems fair to say that the overall theme of Bob's Burgers appears to be family, and the role each member plays within it to maintain a healthy balance. While each Belcher might be just a little bit mentally off-kilter, they're still a family of loving regular (ish) people who love each other. If the program has taught us anything at all, it's that we should love and appreciate our family, forgive them for the utterly ridiculous mistakes they sometimes (always) make, and work together as a team in order to make life just the little bit more fun. And if chanting 'Anus!' over and over again is going to help solidify a family unit, we're all for it.
