R U Professional: "R U Professional" is a 2009 satirical song by the American indie rock band The Mae Shi, inspired by a July 2008 outburst by actor Christian Bale on the set of "Terminator Salvation".  Bale was filming with actress Bryce Dallas Howard when he berated director of photography, Shane Hurlbut, for walking into his line of sight.  An audio recording of the incident appeared on website TMZ on February 2, 2009.  The Mae Shi composed and recorded the song later in the same day, and released it the next day.  The group stated that the piece was created to honor Bale.  The song parodies Bale by sampling his voice from the 2008 diatribe.

The lyrics reference several films the actor starred in, including "Newsies", "Swing Kids", "American Psycho", and "The Dark Knight".
