SAO PAOLO (Reuters) - Two window washers in Sao Paolo, Brazil went the extra mile to make sick children smile ahead of the country's Children's Day celebrations.

The two would wave to children while going about their work at Sabara Children's Hospital, dressed in various superhero costumes - including Batman, The Flash and Spiderman.

"There is nothing to do in the hospital and these activities make a child's day happier," said 9-year-old Laura.

Children's Day in Brazil is celebrated on Oct 12.
