She was a long tall woman in a fat dress

The story:

I love this song, but could never tell what they were saying. I also had heard the earlier line about sitting in a nest with Batman, so I knew something had to be wrong here. When I tried looking up the real lyrics, do you know how hard it can be when you can't pick anything clear out of the song? I even cranked it up and listened hard last time it was on the radio to make anything out. Funny, if they had announced the name of the song on the radio, it would have answered my immediate question. Still wouldn't have helped much with Batman...
