Amos, it was Peter Alsop who wrote "It's Only A Weewee," but I heard Utah Phillips sing it at the Northwest Folklife Festival a few years ago, when he was the featured artist.


Now, as for kids' propensity for relishing the humor in sex-related ditties without always seeming to comprehend what they're talking (singing) about, I recall my neighbor boys (about 7 to 9) back in Toronto, when I lived there, seeming to think this one was hilarious:

Tom and Jenny sitting in a tree,
Tom says, "Jenny, will you marry me?"
First comes love, then comes marriage,
Then comes Jenny IN a baby carriage.    (emphasis added)

I'd say that last line blooper is an illustration of "unclear on the concept." LOL
