Dietrich is perhaps best known for her portrayal of Mother Nature in Chiffon margarine 30-second commercials in the early 1970s (1971-79). Dressed in a gown of white and adorned with a crown of daisies, Mother nature addresses an unseen narrator who informs her "That's Chiffon Margarine, not butter." A perplexed Mother Nature replies "Margarine, oh, no, it's too sweet, too creamy." When the narrator tells her "Chiffon's so delicious, I guess it fooled even you, Mother Nature," Her character, Mother Nature, mistakes the margarine for real butter, and when she learns otherwise, she ominously replies, "It's not nice to fool Mother Nature!", which became Dietrich's trademark catchphrase. The melodic tagline for the ad reads: "If you think it's butter and it's not...it's Chiffon."
