For example, on the TV series "The Big Bang Theory", worn by the character Howard Wolowitz, as well as in "Dinner for Schmucks", where the character Therman Murch (played by Zach Galifianakis) wore an orange turtleneck dickey. Cousin Eddie (played by Randy Quaid) in "National Lampoon's Christmas Vacation" wore a dark green turtleneck dickey underneath an ivory sweater. The character Liz Lemon wore a "sweater" type dickey on the opening episode of season 6 on the TV series "30 Rock".. The character Kent was wearing a dickey in the end scenes of the movie "Real Genius". The dickey is not just a facet of men's wear clothing, it is also used in certain types of cultural dress. Historically, Armenian dress consisted of layers, a result of the variability of the weather, with short and hot summers and long and cold winters. Layers could be switched out easily when changes in the weather occurred. One component of this layering was a dicky style shirt that was heavily embroidered to cover the chest if the woman's outer dress was low cut. It is traditional for Greek widows to wear black to signify their mourning. Historically, widows in certain regions of Greece, specifically Peloponnese and Euboea, "wore a plain white chemise and an unembroidered sigouni with a black "dickey", black headscarf and black apron." Both men and women of the Sámi culture, particularly in the central and southern parts of the Sámi region, wear dickeys under certain tunic styles. The tunics often have a V-neck opening that the dicky is worn under. The dickeys are usually rectangular and are made from wool. Traditionally, women wear red wool while men wear blue. The dickey is usually decorated with reindeer skin around the edges and metallic thread and glass beads in the center. The purpose is for the dickey to be the focal point of the outfit.
