At the end of the song, the lyrics have the following line repeated three times.
Come on superman, say your stupid line.
I think the fact that it is repeated three times is a sign that it is important and not to be overlooked. I don't know what stupid line it is talking about. ¿Does anyone know what it is referring to?
The last part of the song according to lyrics on Google:
Is this what you want, is this who you are? I was doing fine without ya, 'til I saw your eyes turn away from mine He's not going where he wants you Said come on superman, say your stupid line Said come on superman, say your stupid line Said come on superman, say your stupid line
