Shinya! Tensai Bakabon

Showa era gag manga authored by Akatsuka Fujio, both had previously been adapted to anime prior, but in these modern interpretations they are both done by Studio Pierrot. These series have very similar humor and style, in how they are heavily self-aware of the anime industry alongside censorship, despite the source material being relatively tame, these modern adaptations have adult and vulgar humor comparatively. Art direction is also very similar with vibrant uses of color and unique backgrounds. 

Heisei version follows the manga more than the "Late Night!" version. The "Late Night!" one is a gag comedy version with parodies and cameos totally irregular from the manga.
