in the first episode, anal probe, chef sings:
i'm gonna make love to ya woman and lay you down by the fi-yuh caress your womanly body and make ya moan and perspi-yuh we're makin' love GRAVY, love GRAVY, love GRAVY.
yes, it's love gravy, not love baby. he's a chef!
this theme is repeated in the "an elephant makes love to a pig" episode. chef sings a romantic ballad: oh tonight, tonight is right for love, love gravy. then he introduces elton john (this is a joke on the george micheal/elton john remake of don't let the sun go down on me.) anyway, elton sings the same words but ends it with: love grahvah, whoever did elton's voice sure nailed it. now go back and watch those episodes again.
