Oh, I thought you were talking about flop as in "meant to be a series, but due to poor sales they never finished it".
I guess it's not the same, but I've always been amused that Waver and Requiem have English titles, but were changed anyway for the US release.
Hmmm. My definition of filler is slightly different. It's anything used to pad out a season or artificially extend a series' run. So recaps are filler in my book. And regardless of whether or not all of these side stories are actually in the manga, Bleach is getting tiresome for not just...
The first episode of Kuro Ai (Dark Love) has a scene with a preggo Minako.
In the "really really short scenes" category, the epilogue part of Erufina (Servant Princess) has the girls pregnant, but we're talking less than ten seconds or so.
