Ron claims that the city council chairs are Corinthian leather. Corinthian leather is not actually a type of leather. The term was created and trademarked by Plymouth to describe the leather seats in their vehicles to make them sound luxurious. It has never officially been used for any other products.
The plaque dedicated to Jermaine Jackson has his middle name, La Jaune, misspelled as LaJuane.
While Ron is talking about how he never changes he states he has combed his hair the same way since 1978. During season one Ron parted his hair on his right side but ever since then he has parted it on his left side.
