Luke Collis Sienkowski, better known as the great Luke Ski or simply as Luke Ski, is a parody, filk, and rap artist who writes, records and performs comedy music. The decapitalization of the words "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. He had the most requested song on the Dr. Demento radio show in 2002, 2003, and 2011 with his songs "Peter Parker" featuring Sudden Death, "Stealing Like a Hobbit", and "Snoopy the Dogg" respectively. Topics of his parodies have included The Lord of the Rings, Star Wars, Spider-Man, Keanu Reeves and Hamlet. He has, in one song, parodied all the Star Trek television shows. His parody songs are reminiscent of the pop music works of "Weird Al" Yankovic. Luke helped bring parodies of rap and hip-hop to Science Fiction conventions. He does not play an instrument, and sings to pre-recorded music, often in costume or with props. Much of his work satirizes science fiction movies, television, and their marketing and are often from a fan perspective. Many of his longer works are snippets of song parodies collected together into an extended medley, such as Grease Wars or It's A Fanboy Christmas.
