Captain America and Bucky are based on the true story of Chris Evans and Sebastian Stan, two popular subjects of Ok magazine. They became best friends in the 1940s as Donald Duck took over Europe and a giant chicken crashed in the UN. Doodadooodoooaoodododododododododododo was his name. Chris and Seb ate the chicken and burped Doodadooodoooaoodododododododododododo as they had their fair share of blueberry pie before the night closed. I don't know anymore, this is atleast what I remembered when I saw these films.
