What do you get when you cross a farmer, a seductress, and a gigolo? The Nerima Daikon Brothers! These two guys and a gal would like nothing more than to sell out arenas and entertain the masses, but a lack of money and fame make this dream impossible. With the help of lecherous producers, a daikon-stealing panda and a crew of backup dancers, the trio must sing their way to the top and build the stadium of their dreams, lest they stay unknown and penniless forever!
F City, F Prefecture: the battleground where good and evil have finally chosen to decide once and for all who will rule the world…or at least that's the general idea! Neither side seems up for the task, as surviving the brutality of everyday life is enough of a chore. On the side of evil is the organization of Across, its only member the loudmouthed and abrasive Excel who struggles just to put food in her stomach; on the side of good, three disenfranchised, unemployed bachelors whose only pursuit in life is romance. Add in alien invasions, jungle warfare, and Mexican immigrant laborers to Japan, and this war doesn't seem likely to be ending soon!
Excel Saga is incredibly spazzy and not nearly as ecchi, but I think if you appreciate the random comedy aspects of NDB, you'd also like Excel Saga.
Both have the same random humor that is key to Shinichi Watanabe's directional style (Did I mention they both have Nabeshin as a character?)
In the present day, a young group of friends is eager for their band to play in an upcoming festival. Unfortunately for them, the stage has been cancelled! Now, they must race against the clock to convince the mayor to let them play their Canary's song... for fame and glory!
Putting the comedy aspect aside, if watching struggling musicians is your thing, you'd probably like Canary just as much as NDB. It's short, and not spazzy like NDB, but I think you'd enjoy the music aspects.
Meet Mink, the hyper fire-haired teenage daughter of the world's greatest dragon slayer... and dragon! With the blood of both human and dragon flowing through her veins, Mink’s life is anything but ordinary -- especially since she’s in love with Dick, a musical dragon slayer! With enemies at every turn (including the half human/half slime princess Vena), Mink must try her hardest to win the affection of a man who wants nothing more than to see her dead. Can she win the guy without losing her life?
Sousuke Sagara is far from the average high school student - not only is he highly trained in military tactics, he puts his knowledge to use in every single applicable situation (and even those nonapplicable ones.) So, when confronted with high school, he tends to turn average high school experiences into off-the-wall adventures. Love letters become terrorist threats and field trips become commando operations; his survival depends on the watchful eye of his best friend and classmate, Kaname. Together, they may just make it out of high school alive...
These two might seem funny to pair together, but hear me out. Both series rely on quickly paced, crazy humor. They also have plotlines concerning the romances between the characters...usually played for comedy. (Particularly NDB, which doesn't take hardly anything seriously until it starts heading toward the end.) The animation style for both series are bright and bold (although Fumoffu has its darker moments) and they both have some great parodies of other anime and pop culture.
Satsuki and Keichiro are new students of the haunted Amanogawa Elementary School - a school where their late mother attended as a child. Soon they meet the perverted Hajima Aoyama and #1 spirit researcher Leo Kakinoki, and thus their ghost hunting group is formed! WIth the help of Satsuki's mother's ghost diary and the crafty wiles of Kaaya, a cat that has been possessed by the demon Lord Amanojaku, the gang will seal away ghosts in order to rid Kaaya's body of Amanojaku and save the day. Can the four friends manage to seal away toilet ghosts, deadly nurses, creepy dolls and a variety of supernatural phenomena, all while passing their classes?
Note that this reccomendation only applies to the english dub of Ghost Stories.
NDB and Ghost Stories share a similar perverted, gag dub feel. They are both good mindless comedies to watch when you want to laugh. If you liked one of them I reccomend you check out the other.
