Question about a rhyme in a song

I write songs (more, as my grad school advisor quipped, for my own amazement than for anything else) and I hit upon a rhyme that is too good NOT to have been used before: “between us” and “penis.” If it has been used, of course, then I’m just a plagiarist, but I can’t remember seeing it or hearing it before. Has anyone?

RATS!!

(Rats live on no evil star)

This, of course, made me think of Bob, a fantastic song by the man in my profile picture. It’s a short song, too, as it clocks in at just under 2 1/2 minutes.

Oozy rat in a sanitary zoo.

Itself a palindrome.

If you ignore punctuation.

Better a penis between us than a fungus among us.
