Osomatsu-san

While they have their differences, for example, Osomatsu-San is aimed at a more mature audience, (If you're looking for something a little more risque, read the Shichinin no Nana manga. (o_o)) and Shichinin no Nana is somewhat is aiming for a consistant story in the end. They both have the theme of "multiple of the same face living under a roof." (except Shichinin no Nana has one 1 more). All have their own personalities, and they conflict with each other almost every episode. It's also worth noting that each Nana and Matsuno has a unique color to help them stand out. Nanacchi and Jyushimatsu, for example, are both yellow because they are hyperactive and always happy.

While Urusei Yatsura focuses less on the romance on the sidelines, they both have a similar goal of having a supernatural heroine try and win the affection of her love interest, while trying to keep away the competition and deal with their supernatural families too. They both have a similar vibe to them with the comedy as well.
