Before Steve Rogers and Tony Stark duke it out in May’s Captain America: Civil War, Marvel stars Chris Evans and Robert Downey Jr. had a good, ol’ fashioned thumb war during the Kids’ Choice Awards this weekend.

“Are you sure you want to do this right now?” Evans asked his costar after hitting the stage. “Oh, I want it, Cap,” he replied, “unless you’re chicken.”

Watch the mini brawl below.

Evans and Downey seemed to bury the hatchet backstage as evidenced by their GIF game.

Marvelites will get to see the superheroes battle it out on May 6 when Captain America: Civil War hits theaters. The latest trailer teased the impending face-off, along with a massive cast of superheroes, including Chadwick Boseman’s Black Panther and Tom Holland’s Spider-Man.

Other highlights from the Kids’ Choice Awards include John Stamos getting slimed and Star Wars: The Force Awakens winning the blimp for Favorite Movie.
