When Rick Moranis guests on Muppets Tonight in episode 202, he goes to the commissary to seek the advice of Seymour and Pepe. He can't decide which of two sweaters to wear for his "Salute to Late Fifties Crooners, Obscure British Bands, and Bill Withers."

Pepe remarks that the cardigan he is holding in his right hand has a Perry Como feel. The pullover sweater screams "Johnny Mathis!" and scurries away.
