Have you been watching all the fillers? I've been skipping them XD. I get annoyed with flashbacks and flashback fillers.
edit: oh, and the ninja war annoyed me way back when I read the manga. It's still annoying....
Yeah, always watch filler first time through. The war arc lasts too damn long indeed. It'll be a while until I get to see the scene I want to see animated, hopefully I get a good chuckle out of it, like I did from the manga.
I never saw that scene when I was watching earlier episodes. I think what you're talking about happens right after the Pain fight. I skipped a lot of fillers then but I swear I saw it animated!
It should be in the 4xx range. I recall him using it on goddess lady (kaguya?). ---
