Chipmunk Nuts

It's funny how you can think you heard something different that what was said or sung. It is common to mis-hear, but why? Is it because we want to hear the different thing? Or is it because the art of speaking clearly has been lost over the centuries (if this art ever existed in anyone other than over dramatic actors). For instance, I have never been able to hear anything different than "never had another wang on my shoe" in a popular song. If you can't live without knowing, the real line is "walking 'round with little wings on my shoes." I know. It's nothing the same. Now how did I come up with the line I hear? It could be psychological, that I wanted to hear about a wang on a shoe. It could be a hearing problem I have or that I don't listen properly. I could blame the singer and state he should enunciate properly.
