Now that sonograms for pregnant women are common, a new tradition has evolved called the "gender reveal party," in which the family, and often the parents, find out for the first time whether the baby will be a boy or a girl. The person entrusted with this information devises a way to make the surprise happen, often with a cake. The cake inside is tinted either pink or blue, completely covered with frosting or fondant until the ceremonial cutting. Some of these cakes are rather strange. The cakes above took advantage of a joke, while others take gender stereotypes to the max for a slogan.
