Happy high school (1986)

The plot involves the school director bringing in a female inspector to clean up the school. The students decide to kidnap her and replace her with the sexy stripper "aunt" of one of the girls (who is naturally sleeping with several of the guys). The real director meanwhile falls madly in lust with one of her male captors. Meanwhile a goody-good student and her hypocrite father begin to suspect the ruse . . . So will there be a lot of crazy hijinks? Will everything work out happily in the end? Will the entire female cast (and an unfortunate amount of the male cast) find some excuse to get naked?
