Choboraunyopomi Gekijou Ai Mai Mii

Both are pretty random and have short-lenght episodes. The characters also talk a lot and they talk fast. 

Quick and surreal humor style 

Both anime series have really short episodes and both have extremely random moments and humour. 

Both shows are randomly insane with the way they deliver and execute there jokes; along with the short amount of time each episode takes.  

Both are gag comedies with short episodes invloving group of girls and absolute, sometimes even surreal randomness. 

With preposterously fast and maximally absurd back-and-forth, these shorts pack enough into each episode to make you laugh the whole way through. If you liked one, there's no way you won't like the other. (Also, they're both a real treat if you're a seiyuu fan.) 

This is basically Teekyuu but with slower dialogue. 

Both are mini-episode random comedies where a group of girls in a club do very little that has anything to do with the club and instead random nonsense happens all over the place, although Plastic Nee-san is slightly more coherent than Ai Mai Mi. 

Both are comedes about group of girls doing cute and random things. Both are full of gags.. Both have short episodes. 

Crazy short episoded comedies where everything can happen. No real plot, just randomness. Both have same art style and are from same studios. 

Both of them are whacky, 3-minute episodic anime. Both of them make no sense at all. Also, both of them can be pretty trippy. 

Between Ai Mai Mi, Pop Team Epic, and Fushigi na Somera-chan, if you're looking for an anime to watch and you have a quality yet questionable humor and can laugh at the most simple and stupid thing, you need to watch these three animes. Each of the humor presented in each anime I've listed here is enough to make you ascend to an entire new existence as you laugh your ass off and question why you're laughing. They're basically the vines that you see that present raw humor but somehow make a lot of sense and are absolutely hilarious; my example being the "Hi, welcome to Chilis!" So don't let the ratings fool you, if you have the humor to enjoy any of the three animes I listed at the top of this comment, you WILL love the other two. I have no doubt in that. And if you haven't watched any of them, now's a good time to start as they both will make your life more enjoyable. read more 

Both are absurd comedies about school girls 

WTF. Hilarious gags without logic.
