Sorriso nucleare failed to chart in the Italian Top 20.
Sorriso is a municipality in the state of Mato Grosso in the Central-West Region of Brazil. The name of the city means literally "smile", but it actually came from the Italian immigrants who only cultivated rice in the region: "only rice" = "só riso". The words ended up merging themselves to form the name of the city.
