Busily preparing their museum exhibits, we find Lum preparing his speech for the anticipated lecture tour of the museum. As he works on what to say, Abner grumbles about the grind of tending to the exhibits. Now he has to take time away to listen to Lum practice.
Abner gets confused over stone tablets, wondering how many rocks it takes to make up one tablet. They must have had some husky scholars back in those days to tote them to school. Though he vows to keep his thoughts silent, Abner keeps interjecting comments as Lum ditalks about the museum displays.
What other ramifications does having to write on rocks have? Those poor old postal carriers. Their job must have been awful at Christmas time. Cedric enters to add to the interruptions. Will Lum ever get to deliver his speech? Confusion and interruptions continue to the end. Will their museum be worth the price of admission? Abner has his doubts.
