Plastic Neesan

Both shows deals with the daily and surrealistic lives of a trio of highschool girls, and both series are equally bizarre and weird. 

The styles of comedy in each of these are very similar in the sense that they're quite bizarre and silly. They also have similar settings and premises. Plastic Nee-san is rather short (has 12 2-minute episodes), so Asobi Asobase is a great choice if one is looking for something very similar but more substantial in terms of quantity, although -ignoring quantity- Plastic Nee-san's jokes may be a tiny bit more humorous overall. 

Both have great silly humour that isn't like the typical comedy anime with sex jokes in them every episode 

Both stories are about school Both have REALLY same kind of humor and yes, 3 high school girl in the same club. 

Both are gag anime reliant on randomness and funny faces, if you like the humour of one then you'll definitely like the other. 

The randomness and characters just being derps makes them really similar 

A bunch of silly girls do silly things, while making silly faces. 

Some schoolgirls of bizzare school club involved in crazy slapstick comedy events. Every episodes are not related to each other. 

Both shows have all girl characters with crude humor. 

Pretty similar stuff - 3 girls doing crazy things in school. Mad and funny comedies Plastic Neesan is much shorter (~30 min show) - as a result it isn't developed as well and can be considered as "Asobi Asobase in miniature" 

Both shows have female trio of characters, which have crazy ideas and actions 

Both are about schoolgirls partaking in after-school activities and the absurd situations that come with it. They share the same silly humor. 

Both of these animes feature 3 main characters with a comedic plot. Each anime exhibits a specific aura that just engulfs you and makes you want to continue watching. The many bird-brained scenes included in each also have high comedic value and make you laugh. There are also many dirty jokes in each that are unbeatable to other common comedy-centered anime. 

Anime comedy with female characters who will make you laugh while doing push up!!! 

Both shows feature short, random and hilarious episodes with a group of girls as the main characters.  

Same length, packed with absurd comedy and the two feature some mild ecchi. Teekyuu, however, is filled with more seasons when compared to Plastic Neesan. 

- Humor random. - Starring girls. - Everything that happens in everyday life of our characters, who are members of a club, where they lose more time in other things, that in the topic of your club. - Mini - short stories. Where each episode, something new happens, something funny and strange sometimes of form exaggerated. 

Short episodes of insane girls belonging in the same high-school club, but doing (literally) anything other than club activities. 

Both are short anime that feature a group of female students in a school club who rarely engage in their actual club activities, with random and surreal humor. 

Both series consist of half an hour of fast-paced comedy featuring schoolgirls in a variety of shenanigans. Regardless of whether you're out of breath from laughing, or if you couldn't comprehend what was going on at all, you'll be left exhausted after watching.

Un buen monólogo. Ver a alguien caerse. El mejor chiste de la historia. Y ninguno me ha hecho reír tanto como este anime. Hace de las situaciones cotidianas lo más hilarante y absurdo que he visto en mucho tiempo. Si ver al director luchando a muerte contra una cabra no te hace reír, nada lo hará. ------- A good monologue. See someone fall. The best joke in history. And none made me laugh as much as this anime. Makes everyday situations the most hilarious and absurd thing I've seen in a long time. If wtching the principal fighting to the death against a goat does not make you laugh, nothing will. read more 

Both series centre around 3 girls doing absolutely hilarious things. The humour is very fast paced in both series and are also very slapstick. Both are also incredibly funny and are DEFINITELY worth your time! Difference is that Plastic Nee-san is a lot shorter than Nichijou in terms of episode length. 

Nichijou is like a cuter, slightly calmer version of Plastic Neesan; Plastic Neesan is like Nichijou on crack. Both anime use a school setting for a lot of their scenes, and both anime are hilarious. Also, both have girls as their main characters. 

Plastic is also a bunch of very random schoolgirl skits. Nichijo's actually a full anime though, so Plastic will be the length of one Nichijo episode. Worth a quick watch. 

They both have very complicated humor, although Nichijou is a bit more innocent. The style they go about their humor is similar, and conducted well. 

Over the top randomness with some slapstick. 

Both series depend on over the top dramatic humor in an everyday life setting. Plastic Neesan has more of a fanservice vibe and is shorter than Nichijou. 

Like literally they are both the exact same format, short comedy bits (for nee-san its the whole episode and for daily life it is compilations of short clips) Literally every single clip in both serious made me laugh. Plastic Nee-san is only 2 min run time, but still definitely worth it. Danshi Koukousei no Nichijou is literally my favorite anime, both really relate to each other. 

Plastic nee-san is like the girl version of Danshi Koukousei no Nichijou. Both are about highschoolers' life, both are short anime, both present random jokes & both are enjoyable to watch. If you want Danshi Koukousei no Nichijou in an unpredictable way, then watch Plastic nee-san. 

They are very similar animes. Both deal with the daily life of highschool boys/girls in a comical way.  

Plastic Neesan - Centered around 3 girls - They are in a club together - Art is moe (kinda but not too much like "Is The Order a Rabbit?") and the colours are more bright and shiny Danshi Koukousei No nichijou - Centered around multiple guys - They go to an all-guys school - Art is more plain and simple; the colour is more bland Both - Both get caught up in unrealistic, wacky situations - The story revolves around the daily lives of high school students - Both are like the pot of gold of comedy - There are unique characters that probs don't exist in real life, let alone in high school - There's at least one character who is (if not a bit) "normal" Watch them. You'll laugh your buns off for a week. And then you'll go back to your sad life called reality. I feel you, bro. read more
