RMD,
I thought the point was to name a song you couldn't help singing or humming even when the words left something to be desired. At least that is how I took it. I still sing along when I hear it...I just don't think the lyrics are all that great.
You are correct about the version that got all of the air play...but I also know Paul Simon commented as I noted above, and is to be credited for the lyric, especially the "red rubber ball" line.

(Editing to add that they did record the song, but it was not released until the "Old Friends" Album in 2001)
