I went to Oberlin College, and they don't have a film major, but they do have what's called an individual major, where you can sort of pitch to a committee your own course study, and if they approve it, you have essentially just designed your own major.

You should write a song and stick it in there.' And I was like, 'Well, what should the song be about?' And he said, 'The tiger.' 'Oh, okay.' So I went off and I wrote this song. I came back and Todd and I tinkered with it a little more and then we shot it right then. It all happened in a day.
