I never saw much of Samurai Pizza cats. I mean, the people mentioning it seem to be of a noticeably younger generation than me, but yeah, I saw it when I was young, and nobody knew wtf it was about yet. Maybe it aired more often later on?! But anyway, when I was young, I saw a few episodes and liked it, but can honestly say I should have watched more (if I knew when it was on) before really deciding it was a fave of mine or not.
It's really shameful and...Shameful, but back when I was in Grade 4, I pretended to be the pink/red/I forget girl cat and blow-kiss some other student as a "finishing move" after pwning him in some game..Nobody really knew what I was talking about, and I think most kids were laughing at my role-playing as a girl character, but whatever.
I say shameful not because she was a girl, but because idolizing a cartoon character is childish >=P.
