i think this song is very ironic, for the mood it portrays with the rhythm is so happy, kind of childlike free. but the song, i think is about someone trying to commit suicide, but fails, and then the narrator deals with it, trying to deny it and deal with it. And the continuous repetition of this line:
"I, I, I, I just don't know" just expresses the narrator's overwhelming confusion.
