 This is a reference to Cookie Puss, an ice cream cake character created by Carvel in the 1970s.A television commentator opined that the Carvel storyline here referenced the 1973 caper film "The Sting" that starred Paul Newman and Robert Redford, as two professional grifters, who decide to con a mob boss, played by Robert Shaw.In addition, after ordering the cakes with mistakes on them at a Carvel location, Grammer touches his nose as a sign to Jenna and Kenneth, who are outside, that he has ordered them, a similar gesture that Newman did in the film.
