To Help Cancer-Stricken Families, ‘Captain America’ and Omaze Team Up in Hilarious Prank Video

What do you get when you surprise unsuspecting shoppers with a talking Captain America doll, a secret code, and real Captain America actor Chris Evans? One hilarious prank video that’s for a great cause.

On Thursday, Evans and charitable organization Omaze unveiled a new video where the onscreen Marvel superhero surprises shoppers at a Boston comic book store to help him foil a secret Hydra plot. The video begins with groups in the store looking at a large Captain America doll, which mysteriously begins talking to each shopper. The doll eventually enlists the help of the shoppers in an “Escape Room” type of plot where they must follow the clues to discover a secret hidden within the store. The secret? Watch as Chris Evans pranks people:

Yep, Evans himself is hiding in the basement to surprise the shoppers.

“This is the Captain America,” says one shopper as he and Evans hug.

As of the January 19, the Chris Evans pranks video has over 970,000 views.

While the video leads to some good laughs, Evans tells viewers that they can enter for a chance to do an “Escape Room” with him that will benefit Christopher’s Haven, Evans’ charity which “operates a supportive community consisting of nine temporary apartments and a community recreation area for families of children being treated for cancer in nearby Boston hospitals,” wrote Omaze on their website. According to the website, over 300 families to date have been able to stay in fully-furnished apartments across the street from Massachusetts General Hospital while a loved one undergoes cancer treatment.

According to Cancer.gov, in 2014 over 15,000 children and adolescents ages 0 to 19 were diagnosed with cancer. An estimated 1,900 died from the disease.

For your chance to win, head over to Omaze’s website. As Evans says, “Win or lose, best part is that every entry supports Christopher’s Haven. It’s a nonprofit that provides homes for kids and their families battling cancer. It’s a good one.”

You can’t argue with Captain America about that.
