I was re-watching the Sora Jima arc and noticed a claim from Usopp that even for him went a little far. "Nothing's impossible for me" right after Sanji & Luffy kick him at the same time and throw his back out. he then proceeds to throw it back in place, which surprised the two* So I thought I'd just ask the rest of you good people that know the man from his humble beginning to his current state of godliness.
What's the one thing Usopp's said that you can't wait to see come true?
