Lyric discussion by AlisonFowles 

The song must be referring to Erica Jong's novel Fear of Flying. The Narrator and main character is Isadore.

I've been going over these lyrics a lot myself. And I'm really impressed as to how much some of you read into them! However, I highly doubt they are as complex as most of you think. First of all, where the hell do you get the idea of erica being pregnant? Because a baloon is round? Pretty far fetched, if you ask me. Secondly, it's rather obvious who the narator is, there aren't that many options here. Just look at the first few lines:

From what I understand, the character from Fear of Flying is named Isadora, not Isadore.
