Paniponi Dash!

Same studio (SHAFT), same kind of humor, you can even see pani poni references on zetsubou. Lots of references too. Very worth watch if you like Zetsubou or the other way round. 

One word: SHAFT. SHAFT is insane. The somewhat random comedy, the blatant self-referencing, the weird animation style, the chalkboard gags...  

If Pani Poni Dash was super wacky and odd and laugh your ass out aloud funny, then I have one word for Sayonara Zetsubou Sensei- siiiiiiick. It's directed by the same person and the humor and the interesting art style and the humor (I'm really not sure if there's a message or not) will blow you away. Although straight laced people would probably hate this. 

Class of some... oddball girls... A fast paced radical humor based on pop culture references and occasionally a little darker than other "fluffy anime." No plot to speak of though reallyXD Just constant humor and lots of characters.  

Same studio, same director. Both involve a class of eccentric students, and both series contain a TON of Japanese culture references and parodies in every episode. Also, very fast-paced. 

Both of them are Random, School life with wierd teachers and a stereotyping class. 

The Story is actually the same: New teacher has to teach a bunch of students who have their own strong characteristivs and don't mind to interrupt the lessons. the characters are beatly the same, too: class reps, who aren't accepted as class reps, girls with class rep character who aren't; hyperactive and optimistics and so on... drawing: it's the main difference(exept of the age of the teacher xD) in the two animes.While SZS has a less "moe" drawing style and often use pattern to color backgrounds and characters there aren' t things like this.  

Both are Shaft productions, have teachers as main characters, and rely on gags, puns, and cultural references. Just like Zetsubou-sensei, PPD is chock full of lightning fast chalkboard gags. 

Same problematic teacher same problematic students both hilarious same created by shaft  

Sayonara Zetsubou Sensei is pretty much different from Pani Poni Dash, but the one thing both have in common, is the extremely random form of comedy that makes these animes what they are. However, if you like a good plot that continues throughout a series, then these aren't really for you. 

Basically SZS is like PPD with a more darker looking type of tone, but it never gets in the way of the great comedy that equal between the two. 

The same studio, the same director, the same style, the same theme - a weird teacher and his class 

Both were done by the same studio (Shaft) and have similar humor. They also both make references, although SZS doesn't make as many as PPD. 

A lot of references to Japanese and American culture (such as movies, anime, music etc) in both animes. Also, the animes are very random, and fun too watch. 

In some ways, Lucky Star is a more subdued Pani Poni Dash. It is not nearly as off the wall and does not make even half as many references, but like PPD, Lucky Star is big on parody and features a cast of moe stereotypes. 

Both are very fond of referencing other animes, so they're perfect for anime veterans ^^ 

Pani Poni Dash! is great comedy anime like Lucky star ^^ 

A lot of references to anime & games. 

Both are very funny and have a strong random element 

Both anime are practically about the crazy life of school girls. Both make many references to other anime and games as well. 

Paniponi Dash is like Lucky Star but on crack. Both shows have references up the wazoo and it's a great time trying to spot every minor detail. Lucky Star is generally a bit more laid back in tone while Paniponi Dash is wild and hyperactive. I still think that if you like one, then you'll like the other as well. 

Both have a large amount of references to other media, especially to anime, manga and video games. 

Both filled to the brim with references to other anime and games. 

They are filled with randomness, have cute girls as cast, and feature references to other anime and pop culture. They can also be be pretty funny depending on if you like reference humor. 

These shows both feature a cast of cute high school girls, have a similar art style and reference pop culture (Japanese or otherwise) 

Very similar style of humor. Both have a little girl genius among other similar character personalities. Both have a very cutesy art style. Both have great opening and ending songs. 

They're both about school, there's a genius little girl, and both animes get really (and I mean really) random at times. Same type of humor is also used. 

Comedy. These anime are comedy-based, with the most random jokes that the creators could think of. They both have that school, slice of life element. There's lots of energy, and no drama, so if you just want to relax after a hard day of work, then these are for you. 

Along with the parallels other users have mentioned, both Pani Poni Dash and Nichijou have broad casts and each character is given a chance to shine over the course of the show. By the time you've completed each series, you'll feel like the cast is your family.  

both are funny as FiretrUCK 

While Paniponi Dash is a bit more hyper active, the 2 series share a lot of the similar traits and humor.  

Both are rapid-fire, slice-of-life absurdist comedies following the lives of "ordinary" students 

There are many similarities between the two, namely frenetic absurd humour and lots of parodies. They are both somewhat of an aquired taste with some hit-and-miss humour and the plot taking very much of a back seat in both series.  

Both are hilarious and random. 

Both shows are two totally different stories yet have a very similar “out there”whacky and random comedy tone.  

These shows are both random and hilarious, and have tons of references to other anime. 

Both made by SHAFT and both offers the schoolroom comedy with randomness as well as the well planned storyline. 

It is VERY similar to Negima!? in many ways. It was made by SHAFT, features the same craziness that each one offers, even has the whole 'kid teacher' thing going on each with its own ways on making it work out.  

because its all about fun^^ and comedy and can be in real life story there is fighting too which makes it more exiting 

Shaft's Negima is very much a spiritual successor to Pani Poni in terms of style and, when it doesn't take itself seriously, content. The humour is very much on par with PPD and its best moments could easily be mistaken for either show.  

Both have a young teacher at the age of 10  

Both animes revolve mainly around a genius kid of about 10 years old becoming a teacher. Its similar because in both the onli students who actually are involved are females and they always go crazy over the teacher or like to tease them. Both the teachers also have a talking white pet, which is a weasel and a bunny i each case. Mahou sensei negima is more ecchi/fantasy oriented while Pani poni dash! is more of a parody. 

Both shows are from Studio SHAFT and directed by Akiyuki Shinbou. The animation style used for both shows is incredibly similar, even though Hidamari Sketch uses a more simplistic art style overall. Also, I noticed that a few characters share similar quirks with characters from Pani Poni Dash! (Miyako reminds me a bit of Himeko and Sae somewhat resenbles Rei). 

Both by the same people. Paniponi Dash is insane, while Hidamari Sketch is sweet. 

Same director. Kanako and Himeko are practical twins (besides the latter's superior silliness and - presumed - heterosexuality). Mariya might or might not be likened to a vicious and gender-swapped Becky. Matsurika channels Ichijou, down to even the deadpan eyes. Both animes make use of quirky Shindo-isms/SHAFT-isms (immediately recognizable to fans of the man and company). PPD is significantly more episodic, but both have unusual (crack!) humor.  

Self aware and self deprecating humor is relatively common, and both Mariaholic and Pani Poni share this trait. They have a cast of characters that are cliche to an extreme, and their ridiculous, fetishized personalities are constantly lampooned. There is also a certain random and outlandishness that defines these two series' as well. Episodes will often not even complain a discernible subplot, and scenes may shift to ridiculous mascot characters without warning. 

Paniponi Dash was clearly inspired by Azumanga Daioh, having a lot of similar characters and often referencing or parodying the show. They feel very similar on their comedy and situations, often with absurd jokes and kinda random humor. 

Nonsensical comedies with absurd characters and a similar visual style. The director of Hyakko, Fukuda Michio, worked as a storyboarder on Paniponi Dash and countless other Shinbou anime, and his direction on some of the episodes resembles the style of those shows a lot. Torako from Hyakko is also really similar to Himeko from Pani Poni, both voiced by Orikasa Fumiko and acting as the main "boke" of the show. 

Both comedies with chibi teacher characters (although Paniponi Dash's is actually a young genius) and show the daily life with the students that ensues. 

Comedy with fan-spread characters relationship. Center of attention get most airtime, characters from outer scope of interest get relatively lesser and lesser appearance. Minami-ke focused on three sisters, and spread out to respective friends of each. Pretty much the same for Pani Poni, the show focused on main character in 1-C and there are characters from other classes a little bit away from center of attention. Character appearance distribution is pretty handy because all characters get to show off their uniqueness sooner or later, and not all audience are rocket scientists, they don't remember all characters at once. Both show became successful comedy with large casts thanks to this whatever technique. read more
