I'll get the list started:
1.) You've replaced all the framed photos of your family/friends with autographed pictures of the DS stars.
2.) Whenever you enter the small entryway of your house/apartment, you fantasize that you're actually entering your grand foyer.
3.) You find that you have the strange desire to wear pajamas or a nightgown over your clothes rather than getting undressed first.
4.) You find yourself incorporating bits of your favorite DS dialogue into your everyday conversation. (Listen here you, cheap, insufferable pig...
)
5.) You have the uncontrollable urge to wear bows in your hair.
6.) You go to bed wearing your shoes.
7.) You obsess over the DS characters' sex lives more than you do your own.
8.) Whenever you buy a new outfit you find yourself wondering how your favorite DS character would accessorize it.
9.) You frequently don a black wig and think that it alone completely hides your true identity.
10.) You steal some of your kid's Playdough, make a crude fetish doll, and recite incantations over it while staring into a lit burner on your gas stove.
