I remember one time when I was pretty young, I was having a sleepover with some mates, and we were playing some OOT late at night.
We all drifted off to sleep (we knew how to party) but only after we'd made it to the Lost Woods.
So we fell asleep with that damn Saria's Song theme playing while we slept for the entire night. When we woke up, every single one of us had nothing but that song in our heads for about a week afterwards.
All it would take was for someone to start humming it in school weeks later, and everyone would throw their school bags at them.
Such an annoying song. I still can't hear it without wanting to punch a child.
EDIT: Oh my God! Get out of my head! Argh!
