"Samba do Arnesto" (English: Arnesto's samba) is a classical samba song composed in 1953 by Italian Brazilian composer and singer Adoniran Barbosa. In his style of the "paulista" samba, it has humorous lyrics written in poor Portuguese language of the São Paulo city's poor suburbs with Italian immigrants. As is typical of many of his compositions, the last four lines are spoken instead of sung.
