A window washing crew from American National Skyline surprised patients (and their families) at Memphis' Le Bonheur Children's Hospital on Wednesday by dressing up as Marvel superheroes. High fives all around to the crew, whose job is already tough enough, even without the masks.

Growing Up Heroes is the online repository for the young, idealistic, superhero versions of ourselves -- you know, when we dressed as Batman, Spider-Man, Superman, and... Underdog. Everyone's got at least one pic worth submitting.
