Marvel superheroes Chris Pratt and Chris Evans have been having some fun with the Super Bowl this year, and last night they teamed up with Jimmy Fallon to surprise some fans with some hilarious photobombs.

Captain America and Star-Lord’s favorite NFL teams happened to be playing each other in this year’s Super Bowl, so Chris Evans and Chris Pratt took to Twitter to talk a little trash about each other’s teams, which resulted in a bet being made.

Evans went on to win the bet when the Patriots won the Super Bowl, but the two actors decided to team up in Avengers’ style and visit both children’s hospitals. Now they’ve teamed up with Tonight Show host Jimmy Fallon in a photobomb video, where they surprise fans who think they’re just getting their picture taken.

These two guys are something else, and it seems they like to work hard and play hard. If you weren’t fans of them before, it’s hard not to like them now. Despite being two of the hottest stars in Hollywood right now, they seem to enjoy goofing around together like the rest of us.

We can’t wait to see pictures of Star-Lord and Captain America visiting children’s hospitals, where we imagine they’ll have a great time cheering up some very deserving fans. Both of these actors are certainly top-notch, and we’re excited that the children will get a chance to enjoy seeing their favorite superheroes in full garb when they visit soon.

Chris Evans can be seen next in Avengers: Age of Ultron, which will be released on May 1, 2015. Chris Pratt can be seen next in Jurassic World, which hits theaters June 12, 2015.
