Ippatsu Kiki Musume

Similar style of humour,similar situations. Both are crazy and funny,but Kiki Musume more ecchi and not about a schoolgirls. 

Both are bizarre, short comedies that don't hold back when it comes to the dirty stuff. Same kind of humor. 

It's another short series with weird humor. 

Both are crazy, silly, funny, short, over perverted and to be frank really stupid. Stupid in a very humorous way though, when you are in the right mood. Both of them also have low production values and have about the same layout for all the episodes with little variation. Either you loveor hate them. 

Both are short comedy shows that present human health condition using scientific language. While Anime de Wakaru Shinryounaika deals with mental issues, Ippatsu Kikimusume puts the main protagonist in all sorts of circumstances that lead to bodily injuries which serve as excuse to explain all sorts of anatomic details.
