I have officially done...8, 26(1? Try 1 million! *sigh's and goes off into own world*), 36, 37(Hiei's the best)...that's all? Man I need to work on that.
I've got some!
(1) Your room's wallpaper is literally made out of YYH posters and is so thick you can pull the whole thing off and it'll still keep it's shape o.O (one of my friends is really like that!)
(2) You think Hiei is watching/stalking you. (Shamefully, I have almost done this)
(3) You go to the owners of YYH and ask their permission to marry your one of the characters.

hehe...thats funny...i have a few:
you write thousands of poems/fanfics about your fav character, and/or the YYH gang.
you find yourself daydreaming about your O/C killing off your opionion of the worst character.
You find yourself daydreaming aobut the same O/C dating your fav character. and doing other things. Including bearing his child (or if ur a guy, having her bear your child, or if your gay, finding yourself wishing you could bear children (unless you find a contrived way to do so))
