I know that Sogeking is Usopp, but why'd he do it? I didnt see any of the episodes hardly…
Well, you wouldn't have seen any of the episodes, because the anime HASN'T GOT THERE YET.
If you want to see some discussion on it, go to this thread in the manga section
But if you're not reading the most recent manga chapters, this is incredibly spoilerish. I recommend that you find your answers through catching up on the manga rather than just asking.
Oh, and if you don't know where to find the manga, in the manga forum, there is a thread that is called "Where to download One Piece manga".
