My Bride is a Mermaid is quite wacky and zany. It gets a little suggestive at times, but mostly in a comedic way. Lots of references too.
GJ-Bu is pretty great as well. No real story, just a bunch of hijinks. All age appropriate as well.
That's all I can really put. Most of my anime has ecchi in it, not by choice either.
I'll have to agree with everything here if she likes the goofy stuff, though I'll add onto it with my obligatory Ranma 1/2 plug, written by the same person as Bride is a Mermaid if I remember right, I haven't read or watched either of them in a while now...
I also have to recommend GTO as being one of the best lift-up feel better animes out there, except maybe for the first episode, it's sorta weird how it goes about it, but you still get the feel good ending.
Haganai is good, big slice of life about a Friend's Club.
The World God Only Knows turns into a very good anime and is considered by alot of people to be one of the better monster of the week shows out there, but if she doesn't like subs, don't watch it, since if you want to go past the first season, you'll be forced to watch the subs.
Also Aria the Scarlet Ammo is good, except for a few scenes of annoying ecchi/fan service and a running "school uniform turns into a parachute" gag
And finally, a nice mix of fun and dark is Eden of the East.
