Yuru Yuri.

Even thought I found this very similar to K-ON and Lucky Star (way too similar) this is a likable anime and somehow it keeps an original story. I'm not so much into comedy, but I like yuri, I also like kawaii and moe animes so I gave this a chance, and yes, I liked it, and if you like comedy anime, then you'll like this :]

Hope you like~  

EDIT: If you click it for bigger version, it looks way better >_>
