Description[]
Herman's twin brother, Charlie, a fast-talking con artist, stays with the Munsters against Herman's wishes. Charlie has 24 hours to pay back a $1000 loan. He tries to bilk Lily out of $5,000 by attempting to sell her a worthless device that he pretends can separate uranium from sea water. Herman won't let Lily buy the machine.
Grandpa thinks he broke Charlie's machine when he can't get it to produce any uranium. When Charlie hears that neighbor Mrs. Cartwright has lots of money, he sells the machine to her. Knowing the machine is worthless and to protect the Munster name, Herman buys the machine back from Mrs. Cartwright. Grandpa tells Charlie that he fixed the machine, so Charlie buys it back from Herman. But there apparently are still a few bugs in the machine.
