A song is attached.

Brain: From Liverpool harbour always on Thursday, they go there to sail to the distant shores
I: Enough is enough.
M: They sail to Brazil, to Brazil, to Brazil
I: Not funny anymore.
M: And I want to go to the distant shores of Brazil!

A few days later, the song went away. I come to the post office, I need to send a package to a friend who moved to Japan. I came for the second time, the first came to find out the cost of sending.

The postman: I remember you. You wanted to send a package. It seems... right, in Brazil!
I: But not that...
Brain: From Liverpool Havana always on the fourth.
