Window washers disguised as superheroes surprised children at a New York hospital Wednesday, scrubbing the windows of their rooms in Batman and Spider-man costumes as the wide-eyed kids waved.

Two Power Rangers stopped cleaning for a moment to give a window pane fist bump to a young child in a hospital gown at NewYork-Presbyterian/Morgan Stanley Children's Hospital.

Another child's infectious giggles were caught on video as Spider-Man made faces at him through the glass.

NewYork-Presbyterian staff also donned superhero costumers and cheered on the window washers from the sidewalks.
