Sign that you are too fannish, or possibly just a nutter:
Brain: You know that song that's been going through your head for the last week?
Me: Cara Mia? Yeah. What about it?
Brain: It'd make a great songvid! Or icon songset! You should do it!
Me: [ignores utter lack of songvidding experience or talent and goes straight to the important bit] About what character? Dawn?
Brain: No, moron, about [insert fellow fan here].
Me: O.o | Uh, were you hoping to find footage of her on kazaa? Or just ask her to send you home movies?
Brain: Hey, look, on the desk! Chocolate!
Which on examination, might also be a sign of needing to go to bed.
