(CBS) – Holy soap suds, Batman!

Young patients at Lurie’s Children’s Hospital got a super surprise Friday when members of a window cleaning came to work dress in unusual uniforms.

The kids saw Batman, Captain America and Spiderman cleaning the panes of the hospital’s 5,000-square-foot Crown Sky Garden.
