Hmm...I'll Post Some That Has Humor, Bacuse I Don't Know Very Many With Ninjas o Robots:

Fairy Tail
Durarara
Hetalia
D.Gray-Man
K-ON

Tengen Toppa Gurren Lagann has humor and giant robots... Can't think of anything else right now. @_@

The World God Only Knows. It has no ninjas o giant robots, but it has tons of humor and schoolgirls.

YU-GI-OH but tu have to watch from the very beginng series for tu to just amor it

Hmm well mm! is pretty funny,has school girls and sometimes wierd battle robot things...




And yes. That was a DBZ reference.

Giant Robots: Hm, Full metal Panic is good
School Girls: School Rumble
Dragon Ball Z Has Humor and action so yeah hope this helps ^^

Infinite Stratos has humor, giant robots and school girls. Same with Full Metal Panic. No ninjas though :)

Someone already suggested Gintama. No giant robots and school girls but plenty of humor, aliens, samurai and some ninjas.

Mew Mew Power is pretty good

Pretty Cure series is very cool to watch.

Ouran Highschool Host Club has some humor in it. Clannad has to do with school girls kinda ish. Nagima has to do woth school girls too.

Black Butler/Kuroshitsuji. Yes, this doesn't have much of tu dicho tu wanted in the original question, but anyone can get hooked on this. Even though it's historical fiction, it's really funny and really sad and tu can really get into it.

If that's not your cup of tea, then try ~CLANNAD~. It's a really awesome supernatural show.

I hope I helped!
