Sgt. Frog (original title: Keroro Gunsou)

[Yakko Cerviche]

"Kero kero kero kero!"

This show is pretty funny.  For those who haven't seen it, it's kind of like "Pinky and the Brain," but with frogs.  Human characters feature quite heavily in the show as well.  It also contains a lot of pop culture references.  In a manner similar to SPC, the jokes have mostly been re-written as the aforementioned pop culture references, etc. in order to make sense/appeal more to an American audience.  However, this show stays mostly true to the original script.  I could go on for an entire page about characters and such, but I won't bore you with the details.  I encourage everyone to give this show a chance.  All currently dubbed episodes are available to watch (legally) on Funimation's website and Hulu.

Well that's cool, but I still prefer the manga.
Grew up with it, around... 2004 or so. Great stuff, collected all the volumes besides the newer ones.
I think it went on too long, though...
