There are a lot of giant peanuts in the US - and some big Peanuts statues, too.

Outro music is a partial cover of The Peanut Vendor, aka El manisero, which is a Cuban son-pregón - son is a Cuban music style characterized by a certain rhythm, and a pregón is a street vendor's cry. The Peanut Vendor has been recorded over 160 times and was composed by Moisés Simons. It's arguably one of the most famous pieces by a Cuban musician.
