Both series are really similar with the idea of a male protagonist being pestered/bullied comically by a very strange/publicly embarrassing female protagonist that believes in the occult. Both girls make hybrid clubs which a few characters join for various reasons, and along with these people the main protagonist must figure out the story behind this strange girl in order to help her.

Danshi Koukousei no Nichijou

Same sort of random comedic happenstance of boys in high school environments, both ridiculous in many ways. Cromartie is more over-the-top, but not so much to be a completely different idea.

Both are pretty weird, dealing with pushy, loud leading female characters, aliens, and tons of innuendo. Also a sort of half-love story with it.
