1) Fullmetal Alchemist
I don't know if I've ever talked about how watching anime was considered social suicide in my high school? If you watched anime and admitted it, you were a dork. If you cared too much about what other people thought (like me) you watched anime on the DL. Fullmetal Alchemist was one of those shows I watched even though it was so fucking weird.
Years later when I went home for Thanksgiving and met up with a bunch of classmates for a beer, we somehow got into a discussion about anime and just about every single person at the table admitted to watching Dragon Ball Z and not telling anyone. If we had just been up front about this as kids, we probably could've broken the loser stigma.
2) David The Gnome
This was originally a Spanish show that was dubbed to English and put on Nick Jr. in the early 90's. It was my favorite show. I have so many memories watching it. I remember they always showed a preview for one specific episode then never aired it. (It had a dog growing at David's trust fox) Drove little me insane.
3) The Littl' Bits
This one hails from Japan and for a reasonable amount of time I thought I may have imagined the whole thing. No one I knew remembered it. My parents, who remembered David the Gnome and Eureka's Castle couldn't place it either. It wasn't until I discovered IMDb that I realized I wasn't crazy. This show existed and it wasn't a very intricate part of my imagination. I did not go full Tommy Westphall.
