The shirt and blue bracelet that Jesse Woodrow's character wears through much of the movie is for the now broken up Los Angeles band, Deadsy. In the commentary, Woodrow and others involved in the movie state this was because they were freinds and/or fans of the band. Also Paris Hilton made some headlines around the early 2000's for at one point having a very brief relationship with the band's lead singer, Elijah Blue Allman (son of Cher and Gregg Allman).
