The Soup premiered on July 1, 2004 as a spinoff of the similar clip show Talk Soup. Between skewering the worst of reality and scripted television, The Soup also featured a wide variety of recurring characters and sketches, such as the bikini-clad producer Mankini and Lou the chihuahua, who would introduce the Clip of the Week at the end of every show.
