Mr. Holland's Orgy (1997)

Mr. Holland is an out of work musician, whose wife, Rebecca, in an effort to make ends meet, has taken a job watching and reviewing adult movies. This bothers Mr. Holland, so he applies for a job with a local junior college as a music teacher. The only opening they have, however, is for a sex education teacher. Desperate to stop his wife from watching so much porn, Mr. Holland takes the position, only to find that his rambunctious students know more about sex than he does.
