KICK ME IN THE TRADITIONS! (1979)

Based on Leif Panduro's 1958 satire classic. David, a senior high-school student, aims a swift kick at his principal's behind and is committed to a psychiatric ward from the perspective of which he takes a close look at his allegedly sane family. They, of course, are the real loonies. The psychiatrists are worse. Only lovely class-mate Lis is down-to-earth and trustworthy.
