I wondered all the time why Michael Jackson was singing "Beat it! Beat it! No one wants to see your penis!" I figured it must be a song about a guy confronting the neighbourhood streaker.
I had no good answer for Joni Mitchell's "gay pair of guys [who] put up a parking lot." My only thought was, "Okay, well, good for them."
