MST3K episode airing on Pluto.tv right now. Mystery of a flag on the moon as related by one Coleman Francis. Horror/suspense/espionage mashup that appears to have been assembled from at least three totally different movies. Tor Johnson is a rocket scientist turned into a monster by a nuclear blast, a year before the first appearance of the Hulk. Also, a young teen is haunted by the thrifty specter of Ben Franklin and there’s a really depressing (in retrospect) short about Puerto Rico, aka “Progress Island.” Here are some moo cows.
