Before the Super Bowl, Marvel stars Chris Evans and Chris Pratt made a bet, where the "loser" would show up in costume as their Marvel characters at a hospital in the winner's hometown. Since Chris Evans' New England Patriots won the Super Bowl, Chris Pratt showed up as Star-Lord from Guardians of the Galaxy at Christopher's Haven hospital in Boston last month. Chris Evans also announced after the Super Bowl that he would show up at Seattle Children's Hospital as Captain America, with the actor making his appearance at the hospital yesterday with Chris Pratt. Here's what a spokesperson for Seattle Children's Hospital had to say in a statement.

"The hospital was abuzz as Evans and Pratt brought joy to patients and families at Seattle Children's. Much like their superhero alter egos, they saved the day in the eyes of the children and teens at the hospital."

Lisa Brandenburg, president of Seattle Children's, added her own statement.

"We are grateful that real-life superheroes Chris Pratt and Chris Evans turned their sports rivalry into an opportunity to support kids in their communities. We are delighted that patients and families at both Seattle Children's and Christopher's Haven will benefit from these generous donations."

Fans can still donate to both Seattle Children's Hospital and Christopher's Haven through their fundraising websites, or by texting TEAMPRATT for Seattle Children's to 501501 through the end of next week. Take a look at the photos from Chris Evans and Chris Pratt's appearance below.
