Luke Collis Sienkowski (born January 14, 1974), better known as the great Luke Ski or simply as Luke Ski, is an American parody, filk, and rap artist, who writes, records and performs comedy music. The decapitalization of "the great" in Sienkowski's stage name is his own preferred spelling, and the title has appeared as such on all of his albums to date. The name was partially inspired by the Muppets character Gonzo, who often proclaimed himself "The Great Gonzo".
