BAY MINETTE, Ala. Apr 20, 2006 (AP) Three eighth-graders have been expelled from Bay Minette Middle School for showing a pornographic movie in their classroom while the teacher's back was turned.

The students slipped the sexually explicit DVD into the player while the teacher was grading papers and working on a computer, according to Terry Knight, assistant superintendent for Baldwin County Public Schools. The class had been watching an educational video.

One of the students had apparently brought the sexually explicit DVD to class in the past two or three weeks, Knight said.

The three students used a remote control to start the X-rated film on the screen where the educational video had been playing, Knight said.

Another student informed the teacher about the incident.

Knight said neither the students nor their parents admitted to having the DVD.

The students and their parents can appeal the expulsion in writing if they hope to return to the school or apply to finish the year at an alternative school in Fairhope, Knight said.
