Hee hee hee, I think Luna but what do you people think?

Grawp isn't crazy, he's just not very intelligent because he's a giant. I also wouldn't really call Luna CRAZY. She's just a little eccentric.

To me, none of them is crazy.

well none really

FINE! Not crazy and just a bit eccentric or not very intelligent!

I wouldn't call Luna not intelligent.

i wouldn't say that luna is crazy, she's just a bit weird that's all :)

luna, sill love her to bits though!!!

I think Luna LOL

but Grawp isn't crazy .. like they said he's just not intelligent =)

and even Luna is not crazy =P

Luna is so not crazy, she's my favorite girl character! :)

I think Luna IS crazy tbh..

Luna's not crazy, she's just weird. Bella however is insane.

Luna isn't crazy, she is just different

*sets hagrid's hut on fire* *walks on table* *CRUCIO* *sings the i killed sirius black song* i think we get the point.

Luna isn't all that crazy compared to Bellatrix just quirky

Luna isn't crazy, she just believes in a lot of "out there" theories. Similarly, Grawp isn't crazy - he just doesn't know how to interact with humans.

^ Exactly; Luna is just unique.
