Although Bud Westmore is credited as make up artist on each installment of The Munsters, he merely supervised Universal's makeup department at the time. The actual, uncredited work was done by Karl Silvera (Herman's make-up and appliances) Perc Westmore (Grandpa), Abe Haberman (Lily) and 'Mike Westmore (I)' (Marilyn and Eddie).
After the pilot was filmed, CBS execs insisted on re-casting the role of Lily Munster. Initially, both Fred Gwynne and Al Lewis balked at the notion of the part going to Yvonne De Carlo. However, later both Gwynne and Lewis agreed De Carlo was a great comedic actress.
Herman Munster: [reading a poem he wrote as an advertising jingle for his mortuary employer]
When your days on earth are over / And you've gone to your reward, / Let us put you 'neath the clover / At a price you can afford.
