MST3K Ep. 206 - "Ring of Terror"
(Short: The Phantom Creeps, Part 3: "Crashing Timbers") A seemingly fearless college kid must steal a ring from a dead man to join a fraternity.
Catchphrase: Puma? Puma!
The short follows the movie, rather than preceding it as was normally done on the series. This was also the last installment of the serial shown.
