Hayate no Gotoku!, Haiyore! Nyaruko-san W Recommendations
Both are hilarious anime that use outrageous situations to make witty jokes; they don't break the fourth wall, they disintegrate it! Both of them parody other anime.
Many of the characters in both series have a habit of simply blurting out whatever is on the edge of their tongues.
I'm pretty sure that you'll like one if you liked the other.
