I used to be so prepared when the theme songs changed but sadly, not anymore.
Naruto:
*theme song changes*
Me: Wha- AAAAAAAHHHHHHHH!!!!!!!!!!!!!!
Le sister: *laughs*
(This actually happened ;-;)
Fullmetal Alchemist:
Me: Ok, so in exactly 24 episodes the theme song will change.
24 episodes later...
*theme song changes*
