Yeah, I did a double-take when I first read that...
I have a friend who is basically pretty normal, but with one problem: he assumes everything in real life is directly based on whatever stupid game/movie/show/trading card game he's interested at the moment. He thinks ninjas were just like Naruto (they were annoying, wore bright jumpsuits, had goofy '80s headbands, used magic-type stuff, and they had real ultimate power), and so, whenever I bring up ninjas (which, as you should know, if fairly often for me), he says "Oh, like in Naruto?!" And before that, whenever I brought up a phrase like "playing cards" or "monsters" or "cheap hardened paper", he would say "Ooh, like Yu-Gi-Oh?!?!" It's very annoying.
