Detroit Metal City, Danshi Koukousei no Nichijou Recommendations
Both hilariously random with episodes comprising of many short segments.
DMC focuses over the life in a death metal band while DKNN focuses on the lives of highschool boys. DMC is also a little bit more vulgar.
Similar to Danshi Koukousei no Nichijou, DMC also contains a lot of fun moments that can make you burst out laughing. A quick warning though, DMC is very vulgar compared to D.K.n.Nichijou.
