It's MIKE NICHOLS AND ELAINE MAY from their demented classic, "MOTHER AND SON." (Album: "An Evening With Mike Nichols and Elaine May")

The die-hard Dementoids came through on this toughie, with the random drawing selecting Art Brazier, Jr. -- a/k/a Mr. Arthur (Off His Rocker) -- of Springfield, IL, as the winner of a copy of the demented song of his choice!

Imaginative guesses, this time! The most common was "Pam Dawber and Jonathan Winters of 'Mork and Mindy'"!
