Beelzebub 1! It looks like the baby will stay naked the whole time. Good luck to the US company who wants to license this and decides to censor his baby bits.
+ Decent production
+ Doesn't take itself seriously
Quick impression~ This was the only show that had an interesting plot summary. A delinquent, Oga, finds the demon king's baby and to get rid of it, he has to find someone more evil than himself that the baby will like. The baby's demon maid comes to tell Oga that he has to raise the baby to destroy humanity. The baby has some destructive powers when upset or threatened. While not roll-on-the-floor funny, it has likable pre-teen humor. It might be fun to root for a so-called evil character.
