Superheroes sure love washing windows.
One superhero dropping in to say hi would be memorable.
But four? Now that's a day to remember.
On Oct. 29, 2015, Batman, Spider-Man, Superman, and Captain America all took a break from fighting villains to wash some windows at the Children's Hospital of Pittsburgh.
It's a good thing superheroes aren't afraid of heights.
"It effects the children in a great way," Andrea Kunicky, media relations manager at the hospital, told Upworthy.
"They get excited about getting to see their favorite superheroes, talk about it for days, and lifts their spirits up."
This wasn't the first time they stopped by to wash the windows either.
Kunicky said the superheroes have been dropping in since 2012. Their latest visit was just this past April.
And, actually, come to think of it ... these heroes must love washing windows at children's hospitals. Because they've been doing it all over the place!
They've been spotted in San Francisco.
In New York City.
Sometimes they come inside to hang out (like Superman did in Tennessee).
And other times, they even bring along their superhero friends.
Washing windows is practically their part-time job.
And it turns out, they may like it just as much as the kids.
"We enjoy it, too," Edward Hetrick, the man behind Superman's mask in Pittsburgh told WPXI News back in April. "It's not just [for] the kids."
"There are a lot of kids that have problems going on. So to be able to make their day makes me happy."
Window washing may not seem like an activity Batman or Superman would be interested in.
But when you see the looks on those kids faces, it's hard to think of a chore more (super)heroic than that.
