The worst filler episode you ever seen

Just thought I'd make a topic about some of the worst atrocities committed in the land of filler anime episodes. Have you ever sat through an episode of an anime you like and it felt like a slow torture? This is the case with me and a Naruto Shippuden filler episode a while back. When this annoying little brat wasn't letting out a irritating cry-baby wail, he was dancing around like a buffoon all episode long with this ear-bleeding song. Watch a clip of it at your own risk: https://www.youtube.com/watch?v=USOMi8NwXDI So what is the worst anime episode you had to sit through? Extra points for posting a clip of the horror.

I think those feudal Japan episodes during CP9 in One Piece completely take the cake for me. I'll never forget them because the placement was legendary awful. Here comes the final bat... FILLER!!! Bulma hitting up "Fake Namek" was terrible too.

@Arc HAHAHAHHAAAAA!!!! I knew that this topic wouldd be Naruto inspired!! Naruto's had some pretty bad filler episodes but that one takes it to a whole new level of annoying!

Inuyasha isn't actually too bad with it's fillers, even then some fillers have a reoccurring theme or plot to the actually story. But the worst one was episode 91. "The Suspicious Faith Healer and the Black Kirara" I try to skip this one cause it just has no relevancy to the actual story. To me anyways.

The Wolf's Rain recap episodes. The whole series is 30 episodes, but four episodes right in the middle of the series (Ep. 15, 16, 17, 18) are all recap episodes that cover the series up to that point. Not necessarily the worst, but the biggest thing was that considering the studio was BONES (I'm a fan of Eureka 7), I wasn't expecting it. Could've done without those episodes.
