Yet another Centron film about speech. This one comes with an unrelenting commentary by the smart alecks from the Mystery Science Theater 3000 television show.
The wire rack used as a visual aid at 1:45 for holding three cards is amusing. Was it borrowed from a display for the lunch specials over at the campus dining hall?
A speaker shown at 3:40 sounds very similar to the Karl Childers character played by Billy Bob Thornton in Sling Blade.
