That moment in FLCL when a South Park reference was made. I did plus than just smile- I laughed hysterically. There's also another scene where Naota looks like Kenny.
Almost every part from this animé makes me smile... but this scene is what really made me smile... I mean really smile! not because it was funny but because of the mood of the moment, so warm, so sweet... really hard to explain but yeah, that's it X3
