Cromartie High School

Is this the real life? Is this just fantasy? The only thing for certain is that for Kamiyama, Cromartie High School is his reality. And what a surreal reality it is. Because this is where the toughest, meanest (and often dumbest) students are sent to do time. At Cromartie, purple-mohawked bruisers and pencil-chomping street thugs are just part of every day life. And so is a 400-pound gorilla. And a macho brute named Freddie who travels with his own theme music. And, of course, Mechazawa, the student voted most likely to need an oil change. So pack your bags, put on your best tough-guy swagger, and get a lesson in insanity from the hilarious losers at Cromartie High. This is one class you won't ever want to cut. (Source: Discotek)

Arakawa Under the Bridge

Ko Ichinomiya's family motto is "Never be indebted to anyone," but after losing his pants and falling into the Arakawa River, he quickly finds himself in debt to his savior, the cutely insane Nino (who happens to live under the bridge). To repay her, he vows to help her with her desire to "experience love." Along the way he'll meet the river's other residents, including a hot-blooded kappa, a Sister in drag, and a literal rock star. Sorry, Ko—when you fell into that river, I guess you really got in over your head! (Source: NIS America)

Excel Saga

Excel Saga is a one-of-a kind work of art that can only be described as the ultimate parody of anime. From the opening credits - a rather odd spoof of Japanese pop videos - to the ending song featuring Menchi the dog singing/barking a plaintive ballad while a human interpreter translates for viewers, nothing is sacred in the world of Excel Saga.

Walking to school, being bitten by a talking crow, spending time with friends, and watching the principal suplex a deer: they are all in a day's work in the extraordinary everyday lives of those in Nichijou</i>.
