Baka to Test to Shoukanjuu, Kono Subarashii Sekai ni Shukufuku wo! Recommendations
Both have the same setting and moods, not to mention the same type of story telling. Or at least in the sense that at first it seems like they have the same type of objective but then end up doing nothing with it through out the story. The characters and comedy within the story are different but they'll both give you a good laugh, and are different from the rest in the sense that they know where to hit on your funny bone to make you giggle or cry laughing.
simple stupid crazy comedy at its finest.
-Although different world and different context, if you want anime that tell you about pure comedy and joke, this both anime are the solution.
-Both anime contain many hillarious, ridiculous, and idiot comedies.
-Situation and condition created from both anime are full of mess (in funny ways).
-Just watch and laugh.
Both are very entertaining comedys, with good characters. Cant stop laughing some moments.
