Kyou no Asuka Show

Both of these shows are: -short -funny -about Highschool girls -kinda ecchi/perverted humor  

Oshiete! Galko-chan has become well-loved by parts of the anime community for its efforts to demystify and normalize normal parts of the female experience, but I think it's important to remember that Kyou no Asuka Show was doing many of the same things 4 years earlier. While Galko-chan took a broader approach towards dismantling female stereotypes, Asuka Show specifically examines the sexual tensions men experience concerning women, and through its main character these tensions are presented as ridiculous and unnecessary. Of course both shows have a sexually-open blonde-haired main character, and I'm sure that for some viewers that will be enough of a similarity to make a persuasive recommendation, but the similarities between these shows are deeper and more significant than just some surface-level visual similarities. read more 

Kyou no Asuka Show and Getsuyoubi: -Both are short episodes, based on daily life events with fanservice; -The first has a more touch of comedy, while the second the comedy is not prevalent - more like a 'mature' touch, if I were to say; -The first involves the daily events of just one girl, while the second involves the daily events of more than one girl (each girl gets more than 1 episode).
