Ever since the new trailer for "Captain America: Civil War" dropped last week, everyone is taking a side and declaring whether they are #TeamCap or #TeamIronMan. Last night at Nickelodeon's Kid's Choice Awards, the atmosphere was no different, with everyone wanting to know who was going to win in the end, Iron Man or Captain America?

Chris Evans and Robert Downey Jr. appeared on stage together to present the new trailer to the Nickelodeon's Kid's Choice Awards. It wouldn't have been the Kid's Choice Awards if there wasn't a bit of fun and games, so Evans and Downey Jr. decided to settle the "Civil War" like men -- by playing a thumb war.

The videos and gifs of them playing went viral last night on social media, as each actor wore a little face mask on their thumbs. Evans wore a little blue Captain America thumb mask, and Downey Jr. wore a little Iron Man mask. It was adorable, and you can see the full video via THR below.
