lol nah it's after the Winter Soldier (in avatar), Captain America's best friend is Sergeant James "Bucky" Barnes. My best mate is a massive, massive fan of Captain America and by some crazy coincidence my name is actually JB. So I'm sticking with the nickname as my net handle now too. Iron Man kept getting stick & causing too much agro/headache would you believe (not from here)
Mind you now I've learned it's a fine tonic wine, looks like I'm looking for another name!
