“After School Special” (* out of four) was an embarrassingly awful comedy about two high-school morons (Richard Switzer and Ryan King Persaud) who pull a misfired prank on the last day of school and are assigned to a mentor (David Gere) when they discover an underground society with some very dirty secrets which they attempt to expose. Lame script and direction and irritatingly stupid characters give this school comedy failing grades. Eric Roberts, Ron Jeremy, and Jason London all show up in dreadful cameos.
