Peanut butter and mayonnaise?

I don't remember that sensation when I heard the song from the Universal link a few days ago. But I suppose some of the comparisons and impressions are inevitable.

Not sure I ever heard Diana Ross and Lionel Richie do this song as the reported "best duet of all time". I'll have to go see if I can find that someplace to give it a listen. I did like Diana Ross and the Motown sound.
