Royal Rubble

Rockarabians seek the missing heir to their nation’s throne. They know what he looks like: enough like Barney Rubble to be his twin. Ignoring his protests that they have the wrong fellow, the Rockarabians carry Barney bodily to the hotel at which their delegation is staying. Barney begins to think it might not be so bad to become an exotic monarch, until he is told he will have to select many beauties for his harem–something he knows Betty will never allow.
