This episode was singled out for its brazen sexual innuendo. Program Practices requested that Larry Blyden not refer to a girl as "a broad ... really stacked," even though the crudity was essential to establishing the unsavory qualities of Blyden's character. Nor could the protagonist refer to a party as "a ball," since that word had more than one meaning. In another "Nice Place" sequence, a voluptuous young lady (Barbara English) tends to Blyden's every need, then says "Is there anything else I can do for you?" CBS's comment: "Please be certain that the girl's third speech be delivered in a sweet manner, as described."
