Sensei no Ojikan: Doki Doki School Hours

Both series are high-school comedies based on 4-panel manga. Both feature young female main characters who often have a hard time being taken seriously (with the exception that Sensei no Ojikan's Suzuki Mika only looks young, but is actually 27). Both also feature a tall, smart, curvaceous female student who has more interest in cute girls than in athletics, despite the fact that they excel at them. The similarities are almost uncanny.

Both main protagonist's are chibi teachers and story revolves around school / comedy, but Pani Poni Dash! more funny than Sensei no Ojikan though =)
