TEXT: "Japanese performers from the Mangueira samba school parade during carnival celebrations at the Sambadrome in Rio de Janeiro, Brazil, Tuesday. While non-Brazilians have long shelled out hundreds of dollars for the right to dress up in over-the-top costumes and boogie in Rio's samba school parades, few in the so-called ""alas dos gringos,"" or ""foreigners' wings,"" know how to dance the samba well, bopping along goofily in the parades and waving at the crowds of spectators."
