MADISON, Wis. (AP) _ The University of Wisconsin-Madison has apologized to a black student who during a class last year was shown a clip of the movie ``Blazing Saddles'' that features racial epithets.

During a workshop for working professionals last year, an instructor showed a scene of the 1974 comedy in which blacks are shown working on a railroad. Whites call the workers racial epithets and an overseer orders them to sing like slaves.

The student complained and the school's Office of Equity and Diversity, which investigates racial discrimination, got involved.

That prompted an apology in March from the Department of Professional Development and Applied Studies, which offered the course. The apology was obtained by The Associated Press through an open records request.

Department official James Campbell says it was ``an insensitive error to use a video clip that included inflammatory and offensive language, and it will not happen again.''

He says the student was refunded the $230 cost of the workshop.
