Screwballs II, also known as Loose Screws, is a 1985 Canadian teen sex comedy film.

Brad Lovett, Steve Hardman, Hugh G. Rection, and Marvin Eatmore are four get-nowhere boys who are forced into summer school, ending up at Coxville Academy under the supervision of Principal Arsenault.

On misadventures of their own, they decide to go for the ultimate 100-point score, Mona Lott, the new French teacher, but when they are unable to get a shot at her, they end up in the unforgiving clutches of the principal.

The movie is single-mindedly prurient, and scenarist Michael Cory has come up with the lewdest language this side of Hustler.
