The Lone Ranger rides again into action, this time taking on the "Deadly Glassman".
Cristal (Shep Menken, also the voice of Tonto) has stolen what he thinks is a priceless diamond, unaware that the Ranger (Michael Rye) replaced it with a glass replica. How ironic. Rye also voices Cristal's henchman, making this literally a 2-man show.
A commentator on YouTube said that Menken recycled his Clyde Crashcup voice (from The Alvin Show) for Cristal, but actually it was a variation on same.
