Ok, the first one.
I don't have any idea why, but there's Luffy who's trying to break a wall or something with gomu gomu no pistol. He hits, and his hand bounces from the wall and hits Zoro.
And the second one. Luffy's finger gets stuck in a glass bottle and when he asks for help, Zoro comes there with an axe (Or was it his katana?). Luffy naturally freaks out and gets free on his own.
Thank you in advance.
