Jazz-rock group Steely Dan accuses actor Owen Wilson of "dirty work," saying Wilson stole the idea for the film "You, Me and Dupree" from one of their songs.

The New York Post reports Steely Dan founding members Walter Becker and Donald Fagan are asserting on the group's Web site that the idea was stolen from their song "Cousin Dupree," about an aimless man named Dupree who eventually goes to live on his aunt's couch.

The movie "You, Me and Dupree" follows a newlywed couple whose life is interrupted when the husband's young-at-heart best man Dupree, played by Wilson, comes to live on the couple's couch.

Included in the open letter on the Web site, the newspaper said, is an angry rant which says, "They didn't even bother to think up a new (expletive deleted) name for the guy!"

The letter also includes an invitation for Wilson to apologize to their fans at a concert, and then go party with the band.
