This is the third and final appearance of Egghead Jr., and the only cartoon he does not appear with his mother Miss Prissy.
Foghorn Leghorn's name is shown on his mailbox here.
Egghead is reading 'Basic Research in the Physical Sciences' by Prof. Newt Ronn. The professor's name is a play on 'neutron', the subatomic particle with a neutral (or no) charge.
Coonskin caps, as worn by frontier heroes Davy Crockett and Daniel Boone, were a huge must have fad for kids at the time of this short.
Egghead uses the newly emerging (at the time) science of cloud seeding with dry ice to produce his rainstorm.
