One of my typical songs. First I write the opening verse and chorus. It's pretty good, so I write a second verse. It's a bit weaker, but defensible. Then for the sake of "completing" the song, I write the third verse, which is complete garbage, fully intending to fix it some day. Well, guess what? It's 30+ years later and I still haven't fixed it. I'm beginning to think it'll never happen.
Just so you don't have to strain your ears picking them out, here's the verse: I'd like to see you trapped in a cloud-chamber/Then you'd see that randomness is all a part of nature/And when you woke up/You wouldn't feel so much the stranger
To which the only rejoinder is "Huh?" Even I can't tell you what I was thinking when I wrote that (or more likely, picked words at random out of a dictionary). In later years I would just repeat one of the successful verses until I could figure out what I was meaning to say. That might be the lazy way out; it does, however, prevent you from coming across as a complete lunatic.
