National Lampoon's Barely Legal (a.k.a. After School Special)

They couldn't rent it, so they filmed it themselves.

In the tradition of National Lampoon humor comes the story of Deacon, Matt and Fred who will do anything for even a glimpse of sex and spend their mornings pirating porno movies from Fred's after school job at the video store. But when Fred is fired the well runs dry, and our heroes come up with a new plan: make their own adult film.
