Song about Carole

JOHN: OK. I'm finishing the lyrics to "Screw You Carole" and I need another word that rhymes with "Carole". DAN: OK.
JOHN: So... so far I've used... "Clairol", "barrel", "feral", "sterile", and... "NARAL".
JOHN: What? Carole and I had a complicated relationship, dude.... DAN: "Feral"?
