Window washers dressed up as Spider-Man, Superman, Captain America and Catwoman as they cleaned the windows at East Tennessee Children's Hospital in Knoxville, Tennessee, while the patients and their families watched from inside.
"I think it's a great idea because my daughter's been in the hospital for a couple of days, and been in and out, and it was something to make her happy and excited and something different than staying in a hospital bed all day," mother Kyla Rollins told WVLT.
The superheroes also posed for pictures with the children and signed autographs.
"It makes me so happy! It's been a rough couple of weeks with recovery for my daughter, and so just to see a smile on her face means the world to me," Rollins said.

"To be in this room with them and when they turn around to see me and they smile, it's awesome,” window washer Ernest Euleufel told WATE.
