 During the credits, everyone who starred in the special sings "Put Down the  Duckie". And, at the very end of the credits, Hoots comes to Ernie with a  problem of his own and Ernie gives him very simple advice, "You gotta put  down the saxophone if you wanna squeak your duckie". (A homage to "Put Down  the Duckie": "Put down the duckie if you wanna play the saxophone")
