Fats consist of a wide group of compounds that are generally soluble in organic solvents and generally insoluble in water. Chemically, fats are triglycerides, triesters of glycerol and any of several fatty acids. Fats may be either solid or liquid at room temperature, depending on their structure and composition. Although the words "oils", "fats", and "lipids" are all used to refer to fats, "oils" is usually used to refer to fats that are liquids at normal room temperature, while "fats" is usually used to refer to fats that are solids at normal room temperature. "Lipids" is used to refer to both liquid and solid fats, along with other related substances, usually in a medical or biochemical context. The word "oil" is also used for any substance that does not mix with water and has a greasy feel, such as petroleum (or crude oil), heating oil, and essential oils, regardless of its chemical structure.

Fats form a category of lipid, distinguished from other lipids by their chemical structure and physical properties. This category of molecules is important for many forms of life, serving both structural and metabolic functions. They are an important part of the diet of most heterotrophs (including humans). Fats or lipids are broken down in the body by enzymes called lipases produced in the pancreas.

Alfred Matthew "Weird Al" Yankovic (pronunciation: /ˈjæŋkəvɪk/; born October 23, 1959) is an American singer-songwriter, music producer, accordionist, actor, comedian, writer, satirist, and parodist. Yankovic is known for his humorous songs that make light of popular culture and that often parody specific songs by contemporary musical acts. Since his first-aired comedy song in 1976, he has sold more than 12 million albums (as of 2007), recorded more than 150 parody and original songs, and has performed more than 1,000 live shows. His works have earned him three Grammy Awards among nine nominations, four gold records, and six platinum records in the United States. Yankovic's first top ten Billboard album (Straight Outta Lynwood) and single ("White & Nerdy") were both released in 2006, nearly three decades into his career.

Yankovic's success comes in part from his effective use of music video to further parody popular culture, the song's original artist, and the original music videos themselves, scene-for-scene in some cases. He directed later videos himself and went on to direct for other artists including Ben Folds, Hanson, Black Crowes, and The Presidents of the United States of America. In addition to recording his albums, Yankovic wrote and starred in the film, UHF, and television show, The Weird Al Show. He has also made guest appearances on many television shows, in addition to starring in Al TV specials on MTV.
