Kimi ga Aruji de Shitsuji ga Ore de

Both about Butlers and their masters, both reference other anime, and both are very funny. Hayate the Combat Butler is more child-friendly than KimiAru though.

Darker than Black: Kuro no Keiyakusha
|
Both have the same hellish atmosphere to them. They're also similar in terms of series structure whereas Darker than BLACK is a different story every two episodes and Jigoku Shoujo is a story per episode. Definitely worth checking out if you liked one or the other

Tokimeki Memorial: Only Love
|
The same genres and The characters look so much alike (even Tsukasa has the same name). Not to mention the fact that I couldn't help but notice the entire way through that one reminded me of the other. Ichigo is like an ecchi version of Tokimeki Memorial.

Azumanga Daiou The Animation
|
If you add a few guys and some romance into azumanga daioh, you get the premesis for School Rumble. The other main difference is that School Rumble has two seasons, with a third one in production, and Azumanga daioh has one season and a few specials

Lucky☆Star
|
Both are utterly plotless relying solely on the personalities of each of the characters for the comedy. Lucky star is, in effect, Azumanga daioh in a brand new skin.

NHK ni Youkoso!
|
Genshiken is an anime about otaku. NHK is about hikkikomori. hikkikomori and otaku share many traits,and so the animes are similar. Although NHK has a serious undertone to it because it actually looks into the disadvantages and reprocussions of being a hikkikimori.
